Scumbags in ladder

So I've noticed that it's not impossible for me to get a victory in ladder games (quick battles) because as soon as I am about to win or kill a key enemy unit the opponent alt + tabs out and ends the game. This then means he doesn't suffer the defeat and all I get is a draw. CA please fix this so scumbags get the defeats they deserve. Any kind of disconnection should be a loss for the person who drops. Thank you
