No, cuz that be dumb thinking. Just because you have an argument doesn't mean it can be settled by fighting. Like civilized men that we are, we should be capable of settling our differences through diplomancy. And I believe we've moved past the medieval ways of thinking. Witches do not weigh as much as ducks, and might does not make right.
Besides, I don't play ballista, somebody like you (OP), considering the content of the post probably does. So why should deciding that Ballista is the field of battle for arguments? Why can't I choose a place where I feel most comfortable and sure of my skills?
But it doesn't matter, because the entire idea is stupid. It's like that Southpark episode where they get challenged to a dance off. "It's on."
