Have you ever heard people hating on you in a forum for adding randomness to a multiplayer game. And its not even limited to one side- both sides will hate on you. One side, because you "rigged" the game, the other because they can not be sure, whether there victory is down to being lucky. They dont want randomness- they want that sweet Adrenalin shot, when things go wrong and you barely succeed with your head on your shoulders on third try.
