I feel like this can take an eternity to finish, 16vs16 - 5 rounds? I can't see it ending well. Also stairway is a big map and good one to run, I feel we'd have alot of people stalling the rounds, as if we need that, uh, if you can improve your idea, feel free to PM ME, don't reply to this thread;
Until now, I don't see it working.
