No, you're not the only one who thinks that annihilation in PVP sucks at this moment I hope devs change it in 2.4 Arenas patch. I think we can assume that Rage/Focus tree will be nerfed, sooner or later(because of lot of complaining that its OP etc.) So the one viable spec left wil be carnage/combat, but to me it's little bit squishy. I want back my watchman sentinel!
