Presumably those are the people who most NEED switched in order to make the most difference, right?
Team switching and random teams are supposed to prevent people from stacking one team with all the awesome people on one side.
Thankfully, we have a system which now automatically stacks all the awesome people on one side, makes sure I'm never on Java's team, and always ensures the team with the fewest awesome NeoGAF people wins.
Typically the game will say THE TEAMS ARE ABOUT TO BE SCRAMBLED, one person has like 190 points, and then a sniper with 2 points will die and get switched. /rage
