Nobody gains anything from truly AFK'ing
The game becoming stuck has nothing to do with AFK'ers. It happens when someone chooses a color (later playing a Color Change or Irena card) overly slow. And when that Maplestory M Mesos happens, the last thing you should do is stop. The sport out time, 11 minutes after the cards were dealt, and you'll get points as to get a maximum-length game.If you stop you get no points and can not perform for 10 minutes anyway, so you're better off staying in the game and hoping everyone else can too.
