I have seen a few new players here and there but they dont seem to stay long. From the conversations I have had with them they cant seem to get to grips with how to get kills and get sick of being shot down all game they end up leaving for Fifa, MW2 etc
So to all the aces here if you see a new guy in a game dont hammer him so much he doesnt come back!
The guys that I fly with try to “even-up” the missions (Team Battle, CTA, etc) by picking teams and putting a few of the newer players in with some of the veterans so they can learn and at least get a chance to get a kill.
