I wrote a fairly long post about why one stat is superior to another when it comes to both mana regeneration and throughput, in another thread. I got the following response from Mr Ackbarspiff.
Q u o t e:
Applaud.
This is the most comprehensive well written comparison of the important paladin stats i have seen for a long time.
Actually its a shame that you posted it in this thread as the OP is clearly a troll.
This deserves a thread of its own as its actually quite useful when you have to figure out what stats to go for.
You should consider making a seperat thread with this information.
First of all I'd like to thank him for those nice words. Thank you!
Clearly I've also taken him up on his suggestion and I'm posting the information in a new thread.
I have adjusted it slightly to take away the thread-specifics from the other post I made and I've added a little bit of information.
Now, I would ask that if you do have comments or critisisms that you do keep it constructive. Anything else will only get us here:

...or in other words filled with abuse, contradiction and irrelevancy.
Walkthrough of the important Holy Paladin Stats for both Mana regeneration and Throughput.
Mana regeneration Stats
For the Holy Paladin mana regeneration while casting is affected by three stats. Intellect, Mp5 and Crit rating. Let's do an itempoint comparison to see what you get from each stat.
Intellect:
100 itempoints of Intellect will give you in terms of mana (with kings):
1815 initlal mana and increase to your max level.
37.81 Mp5 worth of Mana from Divine Plea (on cooldown)
18.15 Mp5 worth of Mana from Divine Plea (used once per 2 minutes)
16.3 Mp5 worth of mana from Replenishment (90% uptime)
0.72% Crit rating
24 spellpower
Additionally these are possible
7.56 Mp5 from Mana Tide Totem, on CD per Shaman
18.15 Mp5 from Revitalize (Maximum Average, 100% WG and Rejuvination)
4.54 Mp5 from Arcane Torrent on CD (if you're a blood elf)
72.6 Extra mana per Seal of Wisdom proc.
The mana from Crit will depend on your casting model. This is per minute scenarios.
A: 40 HL
B: 30 HL + 14 FoL
C: 20 HL + 25 FoL + 2 HS
D: 10 HL + 30 FoL + 10 HS
E: 0 HL + 44 FoL + 10 HS
To start with, these scenarios assume you're at the Haste soft-cap and that you're keeping up beacon, judgement and SS. (If you're not at the Haste soft cap you'll be casting less than this and the value of crit will go down further)
The Value of Crit in terms of Mp5 for these Scenarios:
A: 9.1 Mp5
B: 7.6 Mp5
C: 6.2 Mp5
D: 5.4 Mp5
E: 3.9 Mp5
So in total: 100 itempoints of Intellect is worth: 1815 initial mana + 24 SP + 36 - 93.5 Mp5 + 72.6 extra mana per SoW proc.
Crit Rating:
Ok, so lets look at Crit rating. For the same amount of 100 itempoints we get 2.17% crit.
Using the four scenarios I already detailed under intellect that gives us:
A: 27.5 Mp5
B: 22.9 Mp5
C: 18.7 Mp5
D: 16.3 Mp5
E: 11.6 Mp5
So in total: 100 itempoints of Crit rating is worth: 11.6-27.5 Mp5 worth of mana returns.
But I remind you that this is at the Haste soft cap. Without any haste at all you would be casting 20.6% fewer heals and it would decrease the value of crit down to 9.2 - 21.8 Mp5
Mp5:
Mp5 doesn't require any complicated models or anything. For 100 itempoints you get 50 Mp5.
Mana Regeneration Stat Summary
If we bring that together you get for 100 itempoints spent on:
Intellect: 1815 initial mana + 24 SP + 36 - 93.5 Mp5 + 72.6 extra mana per SoW proc.
Mp5: 50Mp5
Crit rating at 676 Haste: 11.6 - 27.5 Mp5
Crit rating at 0 Haste: 9.2 - 21.8 Mp5
So it's obvious that Intellect here has the largest potential for mana returns, with Crit being the least interresting.
Throughput Stats
The throughput stats for a Holy Paladin is Haste, Crit Rating and Spellpower. To examine the values of these stats we need a Test dummy, a generic holy Paladin.
With raidbuffs naked a Holy Paladin will end up at about 18% Crit. Since we get intellect on all our gear as long as you're not naked you will have more crit than that. With Intellect from gear and no crit rating you'll end up between 20 and 25% Crit. Let's assume 22% as an average value.
Let us furthermore assume that whatever gear he is wearing will net him 2200 sp raidbuffed.
Beyond this the generic Paladin has zero haste. All other stats are irrelevant to this comparison.
Let us furthermore assume that he has only specced down the Holy tree. The additional crit in the retri tree and the extra healing from Divinity in prot tree etc. is not limited by what stat you prefer. You can spec into them regardless and because of that we'll ignore them.
A lot of Holy Paladins attemt to get and surpass the Haste soft cap so let's use that point as a basis for our comparison. To get the soft cap you'll need 676 Haste. If the itempoints were spent on Crit rating would give you 14.67% Crit. If you spent it on additional spellpower it would net you 811 more.
Thus the Haste and Spellpower focused Paladins will have the following crit amounts:
FoL: 22%
HL & HS: 28%
While the Crit Paladin will get:
FoL: 36.7%
HL & HS: 42.67%
To determine just how much throughput you'll be able to achieve with this you need to know the size of the heals for each Paladin. Note that I am applying the crit rating directly into the size of the average heal.
That means each spell the average heal is:
Haste Holy Light: 12004
Crit Holy Light: 12777
SP Holy Light: 13853
Haste Flash of Light: 4025
Crit Flash of Light: 4291
SP Flash of Light: 5105
Haste Holy Shock: 5790
Crit Holy Shock: 6163
SP Holy Shock: 6677
Now we just have to know how often you can cast the spells.
Cast times
HL with Crit / SP: 1.68s
HL with Haste: 1.33s
FoL with Crit / SP: 1.26s
FoL with Haste: 1.0s
Keeping up Beacon, Judgement and SS will take 6 GCD per minute or 6s for the Haste paladin and 9s for the Crit and SP Paladin. That will have to be deducted from the avilable time for casting actual heals.
For one minute of casting, how many heals can be achieved?
Holy Light:
Haste Paladin: 40
Crit Paladin: 30
Flash of Light:
Haste Paladin: 54
Crit Paladin: 40
Holy Shock: It's obviously limited to the cooldown, so all builds will at best get 10 per minute,
These numbers are of course assuming that no cast is in conflict with keeping up Beacon, SS or Judgement. Furthermore since we're assuming that we keep up SS, we might as well assume maximum FoL Hot use (which is 5 per minute), assuming you're casting FoL at all.
So for straight up spam one minute of casting will yield the paladins the following amount of Raw Healing.
Holy Light:
Haste Paladin: 480 160
Crit Paladin: 383 310
SP Paladin: 415 590
Flash of Light:
Haste Paladin: 217 350 + 20 125 (FoL HoT) = 237 475
Crit Paladin: 171 640 + 21 455 = 193 095
SP Paladin: 204 200 + 25 525 = 229 725
Holy Shock:
Haste Paladin: 57 900
Crit Paladin: 61 630
SP Paladin: 66 770
So as you can see.. the Haste Paladin has the capability of doing more healing than both the Crit Paladin and the Spellpower Paladin and by a fairly large amount at that. The only spells where the crit or sp paladin will do more with is for Holy Shock and the FoL HoT but they are both limited use.
Any combination of spellchoices for healing will give you more throughput using Haste rather than the other two stats in an itempoint comparison.
There is another consideration to make. Once the Haste Paladin has reached the soft-cap he will have peaked his output on Flash of Light. There is no way for him to get any more healing without getting other stats.
Getting more haste will however still give more healing for Holy Light. Just for comparison let's see what the raw healing achievable will become if you're able to double the amounts of Haste / Crit and SP that the Generic Paladin had above. It would mean that the Haste Paladin would have a HL casttime of 1.10s, allowing 49 casts, rather than 40. The Crit Paladin will get another 14.67% and the SP Paladin another 811 spellpower.
Holy Light:
2x Haste Paladin: 588 196
2x Crit Paladin: 404 880
2x SP Paladin: 471 030
Flash of Light:
2x Haste Paladin: 217 350 + 20 125 (FoL HoT) = 237 475
2x Crit Paladin: 180 560 + 22 570 = 203 130
2x SP Paladin: 247 400 + 30 925 = 278 325
Holy Shock:
2x Haste Paladin: 57 900
2x Crit Paladin: 65 100
2x SP Paladin: 75 640
What's notable is that for Holy Light the Haste Paladin pulls away and increase the gap to the other two. 25.3% lead to 45.3% when compared with Crit and 15.5% lead to a 24.9% lead compared with Spellpower.
As we know the Haste Paladin was already peaked for Flash of Light, but even with twice the amount of itempoints Crit rating can't overtake. The Spellpower Paladin will however do so by a fair amount.
By that I would conclude that up to the Haste cap you will benefit more by focusing on Haste rather than Spellpower or Crit. Beyond the Haste cap however it will depend on how you're casting. If you're predominantly casting Holy Light then stick to Haste, otherwise Spellpower might be worth considering.
I hope you've had a good read.
