Just to be clear, I don't really want players to switch teams mid-match to even things out. Blow outs happen; when the teams are unbalanced I tend to allow the match to come to a rapid conclusion -- You guys win, no need in prolonging this. But, then, I hope that the teams get mixed up so maybe the next match might be different -- Hey, teams are different, let's see whether we can do better! For some reason UT3 out-of-the-box preserves the teams from match to match and that totally sucks.
