This game is rated T already, so a few minor cusses here and there wouldn't be such a bad thing, right? It'd help to flesh out a few characters who are more crass or prone to anger.
Champions who could benefit from occasional swearing
Besides, in-game chat is always going to be worse than whatever you could have a Champion say in-game.

Maybe. Fuck if I know.
