I'm not sure if by 'unicorns' you mean they're very rare in pvp, or they're weak. If you mean they're weak; I completely agree with you. If you think they're rare, that's simply not the case. They're the least chosen class, but they still make up a good percentage of the players in the game. The titans supers are nothing compared to the 4-kill blade, the golden gun, and the nova bomb.
