Well, in Impressive Title you could fight one another. But we shouldn't have fighting. Fighting does not settle arguments, it makes them worse. Besides, you can fight in a roleplay, type what your action is.
Yes it would be helpful because there are powerplayers and such, but I think it would cause more lag.
Plus, some users could keep on sending you requests and not stop even though you're declining it. That'd be annoying.
It's a pretty good idea but it also isn't.
