I would like to know why when I play with my roommate, in our college dorm room, Team SWAT usually only pairs us with a 2v3 or 3v3 and sometimes a 2v4 but never a 4v4. Is there a fault in the coding that it just looks for a total of 6 people and doesn't restrict on how many per team? With the exception when we do get a 4v4, 2 of our teams players usually leave during the voting map screen, it continues to load and does not look for another 2 players, thus starting the game 2v4. Doesn't seem balanced properly... Help? Thanks, ~Phil
