I too play SF more than Vanilla or AF. Euro Forces is pretty much dead as only one of the maps was playable. Warlord is good but it gets too laggy if they MEC are pinned down in the palace (64 players in one building... ouch!) So I play alot of Ghost Town (Moders Ghost Town 24/7) or any of the other day maps.

I don't use the crouch that often either. I'm a prone guy too. I'm on in the later evenings (Pacific) usually after 8pm or so. I always check the BF2 Leader Board as it will show if anyone else is playing and where they are.
