I really want them to weigh personal contribution in some way. It really does suck to lose a game where you went 9/0 and spent the whole time on crystal, tactfully retreating, etc only to lose because the rest of my team runs in without the rest of the team.

I've been bouncing around in Gold 3 for a good 8 hours now because of the way the star system works. An endless loop of win/lose/win/lose/win/lose.
