I think that the SunSlinger is the most OP in the game. They can revive themselves and have a Overshield!!!!! other than that none of the Subclasses are OP you just have to learn how to use them and not waste a super on one person. Even if you are going to die. Your super will be better in the long run of the game to get 3 kills and save a flag rather than get one kill ans stay alive for another 20 sec
