What does "Balanced" vocations, actually mean? There is no such thing, the vocations back in 7.4 were balanced, Knight for tanking, Sorcerer for damage, druid of healing & paladin for doing nothing but shooting bolts, this is as balanced as you can get, changing them in anyway is what creates a further imbalance. The problem we have is too many casuals play a Knight because they want to "survive" but then get this absurd notion that they must also be able to dish out damage.
With that said, sounds ok sure, war servers are always fun.
