I always check the opponent team, if they have their clan name I usually just leave. Won't waste my time. I've played with a a friend and his clan before and we dominated the other team so bad that in the last few minutes before we reached the point mark we ran around looking for the opponent team and found none. Then all of a sudden poor souls start getting matched into the game because a lot of them had left and these people were stuck with the horrible loss of the people who were originally matched.
