Ehh I think its more of a "I hate noobs thing". If a player sucks then they're going to suck on fullscreen and splitscreen. If they're good then they'll still stomp on both. With that being said I've stomped tons of people going splitscreen. In fact sometimes I like going splitscreen because I know I'll at least have one competent player on my team. I hate going solo because 80% of the people that play this game suck.
