2x2 Quitters

I've seen lots of posts over the last year complaining about players that quit very early in 2x2 play. Lots of time, they will quit after the 1st push - just 30 seconds. I've played 2x2 long enough to know that an early lead in no guarantee about the match outcome. SC needs to create a penalty for this such as a 5 or 10 minute ban on new games, deduct gold, etc. Other ideas?
