As written by Fallenman of U.S - Malganis:

Please note, this guide is not an all-inclusive raiding guide. It focuses specifically on affliction, due to the fact that affliction rotations are particularly difficult. This thread dissects all information regarding just this aspect of raiding. For more comprehensive raiding, there will soon be a new WOTLK guide. This guide will still supplement that one, specifically for affliction.

The thread here is about Affliction Raiding. This will answer very common questions such as these: Should I use immolate? Should I drop any DoTs from my rotation? What is the rotation? My DPS is really bad, what am I doing wrong? How can I get better at affliction? This will be broken up into 2 posts. The first, below, dealing with DPCTs and whether or not you should be casting all of your DoTs.

I'll start by clarifying what DoTs should be used. The answer simply is, ALL of them. This includes immolate! Affliction is all about efficient use of the Global Cooldown or GCD. If you're not constantly casting something, then you're losing DPS. (this is true with any spec really) But, with affliction, that loss is more noticable. Because affliction is so dependent upon efficient GCD usage, one of the most important things to know for any affliction warlock is called DPCT. (Damage Per Cast Time)

DPCT is a measure of what you get in return for the amount of time used to cast a spell. For example. If you cast a shadowbolt, and your shadowbolt's average damage is 1000, with a 2.5 second cast time, the DPCT is 1000/2.5 or 400DPCT. If you cast a DoT that will do 1000 damage (no matter how long it takes to do that damage), and the DoT is instant cast, then the DPCT is 1000/1.5 or ~667DPCT. (instant casts "time used casting" is whatever the length of your global cooldown is)

So, what does this mean to an affliction warlock? Simple. Shadowbolt is your "filler" spell. IE, it's what you cast when your dots are ticking and none of them need refreshing. You fill this gap with shadowbolts. That said, any dot that has a higher DPCT than your filler spell (shadowbolt) should be cast, because it will mean more dps for you. This is because you get more damage for the amount of time spent casting the spell than you would casting a shadowbolt.

---------------------------------------------------------------------------------------------------

Below, I have listed out the DPCT for all of an affliction warlock's spells, using (22% crit from gear) 40% crit rating, 2000 spell power, and hit capped. This assumes a 56/0/15 build, and the stats are AFTER raid buffs have been applied. (build: http://www.wowhead.com/?talent=IbxMbuMAoqA0IstZE00V)

Corruption:
1080 base damage + ((120% coefficient + 36% empowered corruption + 30% everlasting affliction) * 2000) =
1080 + (1.86 * 2000) = 4800 base damage.
Modifiers:
4800 * (10% improved corruption + 15% shadow mastery + 5% contagion) * 3% malediction * 13% earth and moon * 3% sanctified retribution (ret pally) * 20% haunt * 10% shadow embrace =
4800 * 1.30 * 1.03 * 1.13 * 1.03 * 1.20 * 1.10 = 9874 modified damage.
Pandemic: 9874 * 1.22 = 12046
12046 / 1.5 second GCD = 8031DPCT

Curse of Agony:
1740 base damage + (120% coefficient * 2000) =
1740 + (1.20 * 2000) = 4140 base damage.
Modifiers:
4140 * (10% improved CoA + 15% shadow mastery + 5% contagion) * 3% malediction * 13% earth and moon * 3% sanctified retribution (ret pally) * 20% haunt * 10% shadow embrace =
4140 * 1.30 * 1.03 * 1.13 * 1.03 * 1.20 * 1.10 = 8516 modified damage.
8516 / 1.0 second GCD (amplify curse) = 8516DPCT

Immolate:
(460 base DD damage + (20% coefficient * 2000)) + (785 base DoT damage + (100% coefficient * 2000)) =
860 base DD damage + 2785 base DoT damage
Modifiers:
860 base DD damage * 3% malediction * 13% earth and moon * 3% sanctified retribution (ret pally) = 1031 modified DD damage.
(crit factor) 1031 modified DD damage * 1.40% = 1443 total DD damage.

2785 base DoT damage * 3% malediction * 13% earth and moon * 3% sanctified retribution (ret pally) * 20% haunt * 10% shadow embrace = 4407 modified DoT damage.

1443 DD + 4407 DoT = 5850 total damage.
5850 / 1.5 second cast time = 3900DPCT

Siphon Life:
810 base damage + ((100% coefficient + 50% everlasting affliction) * 2000) =
810 + (1.50 * 2000) = 3810 base damage.
Modifiers:
3810 * 15% shadow mastery * 3% malediction * 13% earth and moon * 3% sanctified retribution (ret pally) * 20% haunt * 10% shadow embrace =
3810 * 1.15 * 1.03 * 1.13 * 1.03 * 1.20 * 1.10 = 6933 modified damage.
6933 / 1.5 second GCD = 4622DPCT

Unstable Affliction:
1150 base damage + ((100% coefficient + 25% everlasting affliction) * 2000) =
1150 + (1.25 * 2000) = 3650 base damage.
Modifiers:
3650 * 15% shadow mastery * 3% malediction * 13% earth and moon * 3% sanctified retribution (ret pally) * 20% haunt * 10% shadow embrace =
3650 * 1.15 * 1.03 * 1.13 * 1.03 * 1.20 * 1.10 = 6642 modified damage.
Pandemic = 6642 * 1.22 = 8103
8103 / 1.5 second GCD = 5402DPCT

And finally,
Shadow Bolt:
730 avg base damage + (85.7% coefficient * 2000) =
730 + (.857 * 2000) = 2444 base damage
Modifiers:
2444 base damage * 15% shadow mastery * 3% malediction * 13% earth and moon * 3% sanctified retribution (ret pally) = 3369 modified damage.
ISB factor = 3369 * 1.085 = 3655. (this assumes 85% uptime which is inline with 40% crit rate)
(crit factor) 3655 modified DD damage * 40.0% = 5117 total DD damage.
5117 / 2.5 second cast time = 2046DPCT



So, as you can see, ALL of your DoTs should be cast. You can use the above formulas to plug in your own stats, including haste, crit, and spell power. For crit, without ruin, you simply cut your crit rating in half, and insert that % into the above formulas. For haste, simply change the cast time to match your cast time. :)


Up next, affliction rotations, and how-to raid as affliction!

Up next, it's time to talk about rotations, and how to raid with affliction. This will also include a section on how to run a WWS parse, and calculate your DoT uptime.

Let's start with what's normally called the "rotation". Rotation is kind of mis-named, since after the initial casting of each DoT, you'll pretty much never cast them all in the same order again, due to the fact most of them have different durations.

Always start with a shadowbolt, and then haunt. Now, many people often ask why you would do this, and some people are even under the misconception that casting haunt after your DoTs is somehow more efficient. Think about it this way: Haunt should have 100% uptime for the entire fight. And since DoTs don't care when the debuff went up (before the DoT was cast, after the DoT was cast, makes no difference), it only matters that the debuff is up. So, why would you cast DoTs first, and have the first several ticks not get any benefit from Haunt? If you're going to have Haunt up the entire fight anyways, wouldn't it be better to have ALL ticks benefit from Haunt? Of course. ;) The same goes for shadow embrace. The first stack is put on by that shadowbolt, and the 2nd stack by Haunt.

So, your intial cast rotation will look like this:

Shadowbolt > Haunt > UA > Immolate > CoA > Corruption > Siphon Life. After that, you're now into what is called "filler" time. (Yes, affliction warlocks should use ALL of their dots. See part 1 of this guide for more information on why.) If your raid does NOT have a moonkin druid or unholy death knight, you will use CoE for your curse instead.

From this point on, your goal is to refresh DoTs as efficiently and quickly as possible. I HIGHLY recommend Asheyla's DoTimer. It is a truly epic mod, and the best mod any warlock can have. You can get it here: http://www.wowinterface.com/downloads/info5302-DoTimer.html

The goal is to refresh a DoT the very moment the last tick expires. For DoT's with cast times, this is done by starting to re-cast the DoT when the amount of time it has left is just slightly less than the DoTs cast time. For example. If your Unstable Affliction has a 1.5 second cast time, you start to cast a new UA when the current one has 1.4 seconds left on the timer. Now, being realistic, obviously it's rare that this will happen. The reason for that is you do NOT want to stand around doing nothing just because you're waiting for that timer to hit 1.4 seconds. It is better to do something, whether that's casting a shadowbolt or using dark pact / life tap. Even if it means you will be a bit "late" refreshing the DoT.

Generally, you do not want to "clip" a DoT. This means refreshing the DoT before the previous one had its last tick of damage go off. And since Corruption is automatically refreshed by Haunt via Everlasting Affliction, you never have to worry about corruption.

Next, there is a reason we cast UA and Immolate together. They both have a 15 second duration, therefore every successive refreshing of these 2 DoTs will always be UA and then Immolate immediately following. You can essentially think of them as just one dot with a 3 second cast time.

And finally, since haunt has a 12 second duration, and you start with Haunt, then UA, and immolate, eventually haunt will work its way around and end up right after you refresh UA and Immolate. When this happens, on the very next "refresh", refresh Haunt early, allowing you to reset the rotation back to Haunt, then UA, then Immolate. So for example, with about 2.9 seconds left on UA's duration, cast Haunt. This brings you to 1.4 seconds left on UA's duration, so you immediately follow Haunt with UA, and then of course immediately again with Immolate.

Oh one last thing. NEVER interrupt a spell cast mid-cast just so you can cast something else. You want to try and avoid that whenever possible.

---------------------------------------------------------------------------------------------------

Now that you have the basics of DoT casting order, rotations, etc, let's work on applying that, practicing, and seeing results for yourself.

To start, a quick explination of WWS (wow web stats). WWS is an online DPS parser. It takes a combat log you record in game, and allows you to see the information in a very useful and detailed format. To create a WWS report:

1. Before you start WoW, browse to C:\Program Files\World of Warcraft\Interface\Logs. If you have a file called "wowcombatlog.txt", delete it!
2. Now, in game, before you start whatever it is you want to log, hit enter in your chat window and type: /combatlog (this will get wow recording your combat log parse)
3. After you are done with everything you want to record, go to http://wowwebstats.com/
4. Click on "Start WWS Client" (note, you may have to quickly sign up for a free account)
5. Click on "Add Combat Log" and browse to C:\Program Files\World of Warcraft\Interface\Logs, and add wowcombatlog.txt.
6. Click on "Host Report". You will now see a WWS report of your combat log!

To help me explain how to read it, I have included a sample WWS report of last night's brutallus. I was fortunate enough to do around 2700dps, though RNG hurt my damage, and it was also a bit laggy.
http://wowwebstats.com/c2fs5tbtygxye?s=140971-173848&a=xb25d6e

Now, let's figure out what my DoT uptime was. To start, we need to know what the total combat length of the boss fight was in seconds. At the top you see the date, time, and length of fight in minutes/seconds. The fight was 2 minutes and 39 seconds long. So, that's 159 seconds.

Next, to figure out DoT uptime, we need to determine what 100% uptime would be for each DoT. This is done by taking the length of the fight and dividing it by the interval of a DoTs ticking. For example, corupption, UA, siphon life, and immolate all tick every 3 seconds. 159 / 3 = 53. So, if I had 53 ticks of each of those DoTs, that would be 100% uptime. To see how many times your DoTs ticked, look under each spell, and look under the column that says "Dots".

I had as follows:
-Corruption: 48 ticks
-UA: 42 ticks
-Immolate: 39 ticks
-Siphon Life: 46 ticks

As you can see, in that fight my UA and Immolate uptime was not quite up to speed. Also, remember that 100% uptime is NOT realistic. Especially if the mechanics of the fight stress execution over DPS via moving around, doing other things, etc.

For CoA, which ticks every 2 seconds, that would be 159 / 2 = 79 (round down). I had 68 ticks, so that's not too bad. To determine uptime, take the number of ticks you had and divide it by the number of ticks you would have had with 100% uptime. So, for CoA: 68/79 = .86 or, 86% uptime. 85% uptime is a realistic goal in a stand-up tank and spank single target fight.

---------------------------------------------------------------------------------------------------

Lastly, I am posting a video of the above Brutallus fight. This will give you a chance to see all of the above in action. Note the video has NO sound, no music, and no editing or any of that jazz. In the video, take not of my DoTimer in the upper right corner. I will add another video later of a test dummy fight, so you have a chance to see a bit more detail of what's going on. Remember: efficient use of GCD's, keeping DoTs refreshed, and ALWAYS be casting something!

Brutallus Video: http://files.filefront.com/affliction+brutallusavi/;12255898;/fileinfo.html

Practicing tips: If you're struggling with DoT uptime, start by simplifying the rotations by temporarily dropping a DoT. Drop siphon life and CoA. Then, practice, and get that rotation down and working. Then, add in Curse of Doom. Practice more! Then, add in Siphon life. Practice practice practice. Now finally, replace Curse of Doom with Curse of Agony again.

<3 that quote.

I've noticed on my affliction warlock, that I get 500 more mana back with, dark pact than with lifetap, so I gotta wonder why you didn't take this talent. I ofc only got 1 point spent in 1/2 imp lifetap so that will have some influence on it, but still that isn't a difference of 500 mana. I understand lifetap scales with spirit and dark pact with spell damage. Well my gear totally lacks spirit so it isn't going to improve til I get other items with spirit on them. My main goal will be items with hit and spell damage so I can get hit capped asap. Stacking spirit is not really what I have in mind. What amount of spirit does the typical level 80 warlock have without epics(just dungeon blues, reputation & quest rewards) if he wants to be hit capped first? Got 215 spell hit in my level 70 gear. I suspect not a whole lot.

Good guide, worthy of a post for sure.

As for Dark Pact vs. Life Tap: Since Dark Pact scales with your spelldamage, it will be far stronger in the start, where spirit is uncommon on the gear you pick up. As you progress with T7 gear (and especially the 4 piece T7 setbonus), Life Tap becomes vastly better.

Its also worth noting that not taking Dark Pact frees up points in imp felhunter to put talents elsewhere.

But dark pact does increase your self sustainability. Lifetap puts strain on healers. Can be an issue on long fights with a lot of aoe damage. In tbc, najentus was such a fight(it was the only fight in tbc where mana on my resto shaman went below 50%). In wotlk, I can imagine sapphiron being such a fight in early raiding.

I would agree with the above poster regardin being able to be selfsustained better with darkpact however in my curent gear my life tap spell gives me about 1k more that darkpact does so in tems of mana per GDC is much better depends on the fight i guess mind you i have a slighty odd build :)

on a side note thanks for the post transfer hadnt thought about the corruption immo thing ... :P

Seeing that affliction is currently the best raiddps spec, this was a nice read indeed, although I do know how to play it already ^_^

First of all, BRILLIANT thread. I've been raiding as affliction for quite a while now, and don't plan to change that anytime soon. I was often debating with myself wether to use Haunt first or last. Now I know a definate answer and will adjust my rotation to suit that. Although depending on my groups DPS, I migt not put all my DOTs in the first trash mob in a raid or dungeon. Just for the simple fact that I could do more DPS by moving onto the second target and fully DOting that up.

But of course, this all depends on the groups DPS and how good the tank can hold agro.

But there is ONE question I would love to know from you and what I think needs to be in this guide. Should I bother geming for crit at 80? It makes sense, because even though my DOTs don't crit, the shadowbolts I blast in between Rotations will. And also, will haste come in handy more due to reduced global cooldown time? Which should I take more?

Get hit capped first, then worry about the rest.

Thankyou very much for the guide, I never used immolate before in my rotation. I was wondering that if this is the case is it worth using the glyph of immolate as an affliction raiding lock? Thankyou very much in advance for any responses.

Tough question, either way you should use corruption and agony.
As for immolate, I really don't know, but I'm more favoured to glyph of siphon life for affliction tbh. I think it will make more effect than the crappy glyph you're mentioning. Why? Cause siphon life is shadow and immolate is fire. Affliction is all about shadow. Need I say more?

Corruption:
1080 base damage + ((120% coefficient + 36% empowered corruption + 30% everlasting affliction)


Wat.

I did some dps testing on a lvl 80 dummy. Fair enough i'm not hitcapped but importantly i've not stacked epix to obtain the highest possible dps, i've just got normal blue gear meaning when i do get epixs and get hitcapped i should pull the same if not higher numbers on a boss target.

http://img155.imageshack.us/img155/8295/dummydpsoh8.png

Almost 7 min fight 2500 dps self buffed. Spec is 53/13/5.

Notice how Immolate in total does almost exactly the same damage as UA. Below Immolate was 10k dmg from lightweave bolt and 20 procs of Pademic but for some reason they only proc for 1 dmg on a training dummy. Pet was doing around 125 dps.

Cast the dots first and they won't get the benefit from haunt or shadow embrace.

Now ask yourself, which is better, non-boosted ticks or no ticks at all.

I have played affliction both on Naj'entus and wotlk and I can tell you that with all the health regen effects you won't put a stress on the healers with tapping (enough to spec dp).

You can use the Heroic lvl 80 dummy with 10 million health to test, affliction spells won't bug out on that.

And Haunt+SB does no damage at all? Point taken though.

Also, regarding the rotation, if you've put any points in Eradication it might be a better choice to make it the first DoT you put up to proc it as soon as possible. Also, if you specced Molten Core it might be a wise choice to put it up as the last DoT (to make sure it procs by the time you're casting it).

Fairly certain that not even destruction warlocks gemmed for crit.

Spellhit > Spelldamage > Spirit > Crit / Haste would be the ideal ratio, in my opinion.

I believe you. But I gotta wonder though, not all healers start with good gear, good raiding experience etc.
- What if the ppl responsible for the healing regen are oom?
- What if the healers are oom or near oom and are prioritizing?
These things can happen on long fights or on fights with mana drain effects. I haven't done any wotlk raid yet, as I'm still busy levelling my 4 chars, so I don't know if there are many fights that fit my description. My guild is working on Kel'Thuzad atm in 10 men setting, only normal mode sadly. Even if there aren't many, current raids are only entry level raids. It are easy fights. Content will be harder in next content patch. I gotta wonder if standard healing regen will still be sufficient then.

Currently though, because of my affliction lock's(this is not my affliction lock) gear dark pact returns 500 more mana. And if there is no discipline priest in the raid, the talents in Imp Felhunter will benefit the raid(including me). So until Lifetap outscales dark pact for me aka I got way enough spirit to outscale dark pact, I'll hang on to my much beloved dark pact. Then I'll consider moving those points elsewhere if I can find a better place to put them in according to my own judgement.
