Leaver Penalty suggestion

Alright people, we gotta be honest with ourselves here. LeaverBuster doesn't do nearly enough to deter players from leaving games. We need to up the penalty for leaving any non-custom, non-Co-op, or normal game. For leaving one game, a player should be disallowed from queuing for another game for 24 hours. This will only effect those who leave games and do not reconnect within 10 minutes or so. If we have a system like this implemented I guarantee that the occurrence of a 4v5 game will go from commonplace to a rarity almost instantly. Naturally, this system should not be in effect when server maintenance is ongoing. Also, for those who disconnect because of internet issues on the player's side, there is nothing that can conceivably be done, because if a system were in place to identity disconnects it could and would be easily exploited.

Constructive criticism only, please. We can compromise on other ideas like this if it seems too extreme, but I personally feel that this is at least a good basis for a system that actually punishes people for leaving games.
