I feel that the game is pretty well balanced. Balance doesn't mean that every super has to be equally effective at killing people. Arc blade is really good at killing people, but the blade dancer doesn't have any decent grenades and invisibility is pretty useless in pvp. Now if you took the blade dancer and gave him the sunsinger's fusions grenades, the perk to carry two of them, the titan's shoulder charge, and the sunsinger's overshield, then, yeah, that would probably be a balance issue. People always point to the fact that many of the top players are hunters as evidence of some imbalance in the game. But I think that it's so hard to say since there isn't any real competitive play in the game. The top players in the game are almost always playing against people who they are much better than. Hunters are faster than the other classes. Maybe all it means is that bad players have trouble aiming at faster moving targets. That wouldn't be the case if the top players were forced to play each other.
