Only tree I don't really see be good for BG's and PVP would be Fury.
Arm's recieved a massive dmg boost, with the addition of execution at any HP on crit it makes for a destructive force.
Prot is sick, both PVE and PVP wise, honestly, as Much as I hate to say it, it should be nerfed a little, but I won't say what aspects. But now we have 4 stuns and one of which is a AoE Stun, and we do decent DPS and we don't take as much dmg....yeah...
I wasn't relly excited about fury, as you need to be well geared for TG to even seem useful and Arms warriors are putting out extreamly good numbers, and with fury you lose MS...
