I would say pally is better cuz you can heal yourself much better than a warrior. Maybe if warriors got combat charge at this level they might be better in terms of mobility but atm pally seems like the better choice.
^^ what they said, imo warrior is much more viable, they can get much more ctc, and imo, their just so much funner :] But... if you go warrior, you Absolutely have to have pocket heals.
