[Penalty For Quitting Matches]

I agree that 10 minutes may be a lot, but with only a 2 minute penalty people will still quit out of games. It doesn't even need to be a time penalty. They just need to come up with something to keep people from dropping out of games on purpose. It is extremely frustrating and ruins the game experience. They could even have a non-ranked queue that allows people to drop and even join mid game for those who want to play solo queue. As it is though, one man down is an extreme disadvantage.

[Penalty For Quitting Matches]

It is rare that I play an entire match without someone quitting on my or the opposing team. Players who actually quit or leave a match should be penalized in some way. I think not allowing them to join matchmaking for 10-20 minutes will help solve this problem.
