I have certain people I'll join teams with but that is only if the teams are even. I also find that a lot of times the team full of friends gets to screwing around with their sprays and other jackassery and lose. I know it's frustrating when its stacked but I generally find some of the better players will jump to another team if it gets ridiculous. My personal rule is if the team I am on blasts through one round and I know it wasn't a fluke, I will switch up teams. Not that I make a difference but I feel like I tried to do something.
