This sort of question comes up in my other RP, but it doesn't really matter since most of our characters are working against the environment and even the strongest fighters aren't as skilled in other ways. My tinkerer George has a lot more usefulness then my Dragonball swordsman Gloria, despite Gloria being much much better at fighting the tougher enemies. If PVP has to happen, I really would like some mechanics to back it up. Otherwise, it gets into a pretty...not-nice situation unless both can agree on something.
