Game leavers

I played DOTA 2 for a while... The best thing DOTA has and League of Legends dont is leavers system. If someone disconnect from the game he have 2-5 minutes to rejoin or he will leave the match. When he leave the match, game is safe to leave. That means that all of us can leave and dont recive afk. Only guy who left the game will get leaver and nobody wont get any XP or LP or lose it.
