Demono nerf was inevitable, but doing it without buffing any other spec is retarded, affliction is dead in PvP, Destro was already subpar post patch and got nerfed without any compensation
I'd love to say that a 33% nerf wont kill the spec but what's the point of having a 2min burst when mage deal the same damage every 10sec
Also, considering War/Feral/Mage can pretty much kill people by just looking at them in arena, it's safe to assume the reason it got nerfed was AOEing down people in RBG
