I'm in the position where I'm starting to consider replacing T12 gear with some higher iLvl stuff.
My tank never got a 4pc T12 Bonus. So effectively it's just a DPS buff that I'm getting from T12. (For reasons unknown to me - Paly Tank 2pc Bonuses in both T11 and T12 were DPS bonuses - not Tank bonuses.) I think that's fairly straight forward. If the Non-Tier stuff has better stats (Tanking) then it should be replaced.
But what about my DPS stuff (Ret, Arcane, Shadow). Is there any way to determine the relative value of having a 2pc bonus vs possibly higher iLvl gear without the bonus?
Example: Arcane. I get a single mirror image. Is it wort replacing that bonus with gear with more INT?
Anyone know a way to measure that sort of thing?
