Actually, I saw some rules posted on EA's website that says server admins can't run pistols/knife only servers, nor can they restrict kits of any kind. EA's way of taking your money then kicking you to the curb.
You'd be surprised at how many people will actually play by the rules. Fizzy and I played several pistol only matches and only a couple guys were trying to ruin it, it was still a lot of fun. We rented the servers, so the hell with EA trying to dictate how
we can and cannot play.
I'd love to, but the last "pistols only" match I joined was full of people just using AR's. I felt out of place being the only dude using my pistol and so I just switched to my primary. These things never go according to plan unless the game is like Ghost
Recon and you can lock weapons.
