"there used to be a rule stating that hiding your armband or acting (citing from memory) in a way that makes the other team reasonably think you are eliminated was a reason for elimination. I used to warn players before a game that they would be pulled using this rule, since I'm very strongly against DMW (I think it only encourages overshooting).
That rule is gone now replaced (somehow) with the one that states that not having your hand on your head constitutes a playing-on."
I cant seem to find anything about having your hand on your head...anyone?
