Yeah, I followed the discussion on Twitter that they didn't like too many players, afraid that it would turn into grenade spam. I always wondered how that other awesome shooter and succesor to the Delta Forces, Joint Operations : Typhoon Rising managed to cope..
Oh yeah.. 150 players and large .. awesome and LARGE maps.

Large maps = no grenade spam (unless you have GL weapons with unlimited ammo. )
Please DICE, I know your playtests focus on some frantic close quarter combat situation, but the cool thing about karkand was that you could move everywhere around the map if you wanted and not be afraid about one single sniper pwning everyone.
