^^The above means that OP classes/specs such as Warrior, Mage, Retardin and Shadow Priest will continue to have extreme burst, while classes that already had no burst at all, such as Rogues, will have to contend with 50% LESS burst than what little they used to have.Originally Posted by Blizzard
So what happened is, Blizzard chose to nerf everyone instead of just nerfing FOTM classes/specs.
The new nerf will probably get Rogue from 1-2% Arena/Rated BG representation to less than 1%. The class that used to be synonymous with "burst" once upon the time, now is the prime example of sustained DPS, thus making the class quite useless in PvP, where burst is king.
Yet another great move by the pr0s at Blizzard.
