Let's make a comprehensive list of specs and required hit % for those out there that want to know.
Here is what I know of melee: Sub/Muti Rogues: 17% Enh Shaman: 17% Frost DKs: 17% Fury Warriors: ~14% Arms Warriors: 8% Ret Paladins: 8% Unholy DKs: 8%
As far as I know all casters need 17% spell hit cap. Except the aforementioned Atonement spec'ed Discipline Priest. -- Mcbrain, Goblin Shadow Priest, [Lock Down], Kil'Jaeden
