So you're saying a vanguard is hard to play? Ranged aoe taunt, multiple hard stuns, multiple ranged interrupts, lots of ranged aoe damage and lots of interesting snare/immobilization procs that you don't have to directly activate? Mine's only 45 and I mostly just play him when I'm bored (don't like the classes style) but it's not difficult to play and it's plenty useful in wzs.
multiple hard stuns = 2
multiple ranged interrupts = 0 (unless you count gap closers - 2)
sorry, vanguard tanks are the worst of the 3 tanks when it comes to pvp :\
