Q u o t e:
I would love to see same thing done with pre-raid Ret and prot gear.
Can't help you with retribution, but I can tell you what I'm aiming for for Protection. It's what I'm gonna gather, I'm not saying it's the best gear out there. I'm rather oriented on crushing blows, which might or might not be your thing:
Weapon - Continuum Blade - Keepers of Time: Revered
Shield - Shield of the Wayward Footman - World Drop
Head - Helm of the Righteous - The Mechanar: Pathaleon the Calculator
Shoulders - Spaulders of the Righteous - The Botanica: Laj
Chest - Jade-Skull Breastplate - The Mechanar: Nethermancer Sepethrea
Wrists - Bracers of the Green Fortress - Blacksmith
Hands - Gauntlets of the Righteous - The Shattered Halls: Warchief Kargath Bladefist
Waist - Lightwarden's Girdle - Quest Reward: Deathblow to the Legion
Legs - Timewarden's Leggings - Keepers of Time: Revered
Feet - Boots of the Colossus - Mana-Tombs: Pandemonius (Heroic)
Libram - Libram of Repentance - Vendor (15 Badge of Justice)
Neck - Strength of the Untamed - Cenarion Expedition: Revered
Back - Devilshark Cape - The Steamvault: Warlord Kalitresh
Finger - Elementium Band of the Sentry - The Arkatraz: Harbinger Skyriss
Finger - Protector's Mark of the Redemption - Quest Reward: Dissention Amongst the Ranks...
Trinket - Figurine of the Colossus - The Shattered Halls: Warchief Kargath Bladefist
Trinket - Dabiri's Enigma - Quest Reward: Dimensius the All-Devouring
Enchants:
Weapon: Enchant Weapon - Major Spellpower (40 Spell damage) - Enchanter
Shield: Enchant Shield - Shield Block (15 Block rating) - Enchanter
Cloak: Enchant Cloak - Dodge (12 Dodge rating) - Enchanter
Head: [Glyph of the Defender] (16 Defense rating, 17 Dodge rating) - Keepers of Time: Revered
Shoulders: [Greater Inscription of Warding] (10 Defense rating, 15 Dodge rating) - Aldor: Exalted
Chest: Enchant Chest - Exceptional Health (150 Health) - Enchanter
Wrist: Enchant Bracer - Major Defense (12 Defense rating) - Enchanter
Hands: Enchant Gloves - Major Spellpower (20 Spell damage) - Enchanter
Legs: [Runic Spellthread] (18 Stamina, 27 Spell damage) - Tailor
Feet: Enchant Boots - Boar's Speed (9 Stamina, 8% Speed increase) - Enchanter
(Scryer would give 5 more Defense and 5 less Dodge, making it very slightly easier to reach the 100% cap, but have more block attributed for that, causing overall very slightly less damage migitation).
Total:
Armor: 10114
Strength: 52
Stamina: 456 (+27 from enchants = 483) (+150 health from enchants)
Intellect: 87 (+4 socket bonus = 91)
Defense rating: 297 (+38 from enchants = 335) (+6 socket bonus = 341)
Dodge rating: 74 (+44 from enchants = 118)
Block rating: 73 (+15 from enchants = 88)
Block value: 115 (+6 socket bonus = 121)
Mana/5seconds: 13
Damage and Healing: 208 (+87 from enchants = 295)
Spell Hit Rating: 8
Speed Increase: (8% from enchant)
Reasoning behind this gearset is pushing crushing blows off the table for lvl 73 mobs. I'm assuming you have the Anticipation and Deflection talents, which add 20 Defense and 5% Parry.
2.4 Defense Rating = 1 Defense (@ 70)
60 Defense Rating = 1% Miss, 1% Dodge, 1% Parry, 1% Block, 1% Anti-Crit
Miss% = 5% + ((Defense skill - Attacker's attack skill) * 0.04)
Against lvl 73 mobs: -9.6% + 0.04% * Defense
With 370 base defense: 5,2% + (Defense rating / 60)%
18.9 Dodge Rating = 1% Dodge (@ 70)
Base dodge + (AGI / AGI:Dodge ratio) seems to be 4.17% for a lvl 70 human with no agility from items.
Dodge% = Base dodge + (AGI / AGI:Dodge ratio) + Dodge Rating contribution + Talent and Race contributions + ((Defense skill - Attacker's attack skill) * 0.04)
Against lvl 73 mob: -10.43% + (Dodge rating / 18.9)% + 0.04% * Defense
With 370 base defense: 4.37% + (Dodge rating / 18.9)% + (Defense rating / 60)%
31.5 Parry Rating = 1% Parry (@ 70)
Parry% = 5% base chance + contribution from Parry Rating + contribution from talents + ((Defense skill - attacker's weapon skill) * 0.04)
Against lvl 73 mob with Deflection: -4.6% + (Parry rating / 31.5)% + 0.04% * Defense
With 370 base defense: 10,2% + (Parry rating / 31.5)% + (Defense rating / 60)%
7.9 Block Rating = 1% Block (@ 70)
Block% = 5% base chance + contribution from Block Rating + contribution from talents + ((Defense skill - attacker's weapon skill) * 0.04)
Against lvl 73 mob with no talents: -9.6% + (Block rating / 7.9)% + 0.04% * Defense
With 370 base defense: 5,2% + (Block rating / 7.9)% + (Defense rating / 60)%
Chance to prevent curshing blow/regular hit = Miss% + Dodge% + Parry% + Block%
Against lvl 73 mob with 370 base defense: 5,2% + (Defense rating / 60)% + 4.37% + (Dodge rating / 18.9)% + (Defense rating / 60)% + 10,2% + (Parry rating / 31.5)% + (Defense rating / 60)% + 5,2% + (Block rating / 7.9)% + (Defense rating / 60)%
Against lvl 73 mob with 370 base defense: 24,97% + (Defense rating / 15)% + (Dodge rating / 18.9)% + (Parry rating / 31.5)% + (Block rating / 7.9)%
With these enchants: 24,97% + (341 / 15)% + (118 / 18.9)% + (88 / 7.9)% = 65.08%.
Holy shield wit the libram adds 35.06% block rating, leading to 100.14% while Holy shield is up.
Note that Tier 4 gear and the occasionally lucky epic will provide better defense/parry/dodge/block, resulting in more than 100%, which means I can replace certain items by items with less defense/parry/dodge/block and more stamina/spell damage.
In addition, I counted the socket bonuses, but not the sockets themselves. You can use the sockets to boost stamina and spell damage.
Lastly, this is a little reworked version of my own post on my own guild forun which was primary written for only myself in mind, and not really written as a guide, hence the weird format and focussed addressing. If anyone writes a more generic guide, I'll take this off.
