Early game disconnects shouldn't affect my MMR

Hey everyone, just a quick suggestion, it's really annoying when you start a ranked game and someone dc's or quits right from the start (for whatever reason).

In dota if there is a leaver in the first 5 minutes of game then the game doesn't count and people can leave. I know this isn't perfect and I don't suggest doing it as is, but a version of this would be great...

Now... don't get me wrong, if you are losing and leave it won't matter because its only the first 5 minutes or so. The only real issue I see with this is leaving the game like a 'dodge' but then the penalties should be worse than a dodge (it should count as a loss for the leaver, and not count for the rest, I mean, no win or loss for anyone other than the leaver including the opposing side). I also can see this being used as a boost type thing. If that's the case, then anyone you queue with should get the loss (so if you queue with 2, 3, 4 or 5 people, then you all get loss).

I really think we need something similar and hopefully you guys can come up with a better version.
