Yes thats what I meant only do it only once for the first time that player is joining bluYou should only have to do it once while connected to a server, otherwise auto balance would piss a lot of people off, map change would obvious reset this.
Make a system were it only kicks in with maybe like 12+ playersdoesn't seem too bad, but what about people who just go blu to fill the team. What if you're on a less populated server and nobody can join blu because of this feature
