Someone posted that you can dodge/parry debuffs from bosses. Basically if a hit that has a debuff attached is fully avoided not only the hit will miss but the debuff will not be applied aswell. Another cherry on the avoidance cake.
Personally I will go all out on parry, ignoring mastery completly. This brings avoidance, high crit, more HS procs, longer barrier uptimes and a better chance to avoid debuffs. You still want to use shield block though. With all that crit you don't want to miss out on 50% SS damage. At least in single target scenario. On multitarget your avoidance will make Revenge spamable so I would use barrier then.
Mastery has nothing on the table that puts it on par.
Btw has someone a damage comparsion of SS/Revenge?
Revenge hits up to 3 targets. But afaik the split damage is reduced. Has anyone got current numbers? Afaik the main target will get 100%, the second 50% and the third only 25% damage. But not sure. Maybe the damage is split evenly on all 3 targets like Thunder Clap.
Edit. I found it. Source: http://us.battle.net/wow/en/forum/topic/6794029542
Revenge now deals 50% damage to a secondary target, and 25% damage to a third target.
Is this nerf still in place?
So a Revenge is either 100%, 150% or 175% of its damage. Depending on targets hit.
