If it hasn't been said before it can be said again: Adding a dojo to wushu doesn't fix the problem. You can still run in dojo mods (CC: lenshu3ng), additionally: part of the beauty of wushu is that it's free form no dojo provides battles between players that can travel thousands of distance without either player really "running".

That's not to say boxshu, as it's called right now, isn't a good or fun mod. It's just to say that your idea doesn't actually really solve the problem, but in fact hurts the basis around the mod. Additionally: if you don't want to win or lose to a cookie cutter wushu opener, I recommend you just put yourself in a position where no rush kick or punch can hit you.

Finally- you have too little faith in the community. When there's a public wushu tournament, wushu players also congregate. So while there may be newer players to the mod using their YouTube/Wiki openers and then running away, there will be plenty of [fl0w], [RelaxAll], [Alpha], [impro], and freeagent wushu players like Omiwom, Wooooooooo, Dislocate, etc. who are playing with higher integrity than that. The wushu players still won those tournaments, because there's a reason those openers aren't gamebreakingly good and used in top level play.
