I have been paired up with the worst teams possible. I am in a clan of 20-something, and usually 2-3 people can join a party. Sometimes, those people are doing other things. When I play by myself, I get paired up with the absolute shittiest teams ever. I am never able to really say "Oh wow, my team's really doing well!". I lose, and lose, and lose. Either the teammaking setting is screwed up, or people are making uber clans and the game wants to pair me up with them. It's a surprise I have a 1.58 after being put through so many losses.
You could try mercenary mosh pit......that's how I roll!!!!!!!!!!
