I've played three games myself so far and each time Red has one. I agree that it might be unbalanced a bit too much in favor of Red Team.

This shouldn't be allowed. You're screwing over other players and ruining it for everyone. Leaving a game early once is fine because you might have something to do but constantly bailing out should result in a temporary cooldown from joining. A great example of what I mean is the system in CS:GO. It's been years since I last played it but if I remember correctly it went like: abandoning a match once leaves you with no cooldown. Leaving a match twice gives you a 30 minute cooldown. Leaving a match 3 times is 2 hours, 3 times is 24 hours and 4 times is a week and it would reset something like every week or two. I've stopped joining because in 2/3 of my games someone left and at that point there's no reason to try since you can't win so goodbye my gralats.
