The only nerf I've noticed when I play my Warrior is just moblity, not being able to intercept is shithouse, but you can still pump out a shitload of damage in arms if you're single targetting, to answer your question! arms I believe is still way better but if you wan't to go fury use 2h's, due to the mobility nerf you get kited allot more unless you have dispels on you constantly, so yea with fury roll 2h's because when you hit the target you want to be hitting for as much as possible before that next nova/blink/deepfreeze comes. Next patch Arm's wars will see a slight increase in damage and just a tiny bit more mobility due to the cooldown of charged being able to be glyph'd/spec'd down. War vs anything caster is pretty much game over next patch when spell reflect becomes a 30 sec cooldown rather than 10 secs. IMO roll another class if you have trouble playing arm's on your warrior.
