Well, that's good at least. I didn't think there were that many queuing, since even when they didn't afk out, it seemed like they had to wait a rather long time for a queue pop. Maybe that's because it's a group queue for them.
I'd still be concerned about the effect on the community of quitting early, but that's harder for most people to understand I suppose. Not as concrete or immediate of a problem. I guess it just seems like if getting games is the highest priority, getting a loss now and then is the least of one's concerns. I mean, it's not like people don't know when they've beaten somebody. And quitting as soon as you've decided you can't win seems to encourage... I suppose you might call it 2-dimensional thinking. The best games I ever played were where we went down 0-2 and ended up winning 3-2, often through a change of strategy.
