It is better to always have mod working on pvp contents too and risk in order to have the maximum fun given by the mod, even if just for few hours or one day in case of ban, which main purpose is to have an edge over others players and not to cheat on offline content against idiot bots with no fun. I am sorry that my tone seem harsh, but i don't mean to offend you as a personal attack, i just said an objective truth as it Is. If pvp is not moddable at all for other reasons then write a note saying that so players can read it and decide before installing.
