What? Noooo!
Seriously, this feature has ruined good lobbies for me. If you join a game with friends, and the ships shuffle about, after the third game, you might end up on the wrong team and have to back out to lobby and start all over again. Really, I don't understand this feature at all. If you're having fun in a lobby, why get forced out of it after 3 matches? It's turning into a session-ender for me.
Also, It was a curious decision to have the default option at the end of a match as 'return to crew form' rather than 'rematch'. 99% of the time, I want to rematch. If I don't, I will just leave the lobby and re-crew manually. Forcing you out of the game just makes me realise that I have more important stuff I should be getting on with. I'm sure there's some logic behind it, but I really can't see it.
