I turned off theater mode and try to only join 50ms rooms. It makes a huge difference. Theater mode isn't that great anyway, because it doesn't actually show what happened on your screen unless you're the host. And even then it's still weird.
Akimbo FNG9s destroy everyone, especially with steady aim and SOH pro. This is the best secondary without a doubt. Steady Aim is extremely good in this game.
I hate the fact that the handguns come out so slow.
The switch should be instant, even without SOH pro. They're so bad. Come on Infinity Ward, at least give me a reason to use them.
Also, sniping is fun again. Say what you want, but it's a game. The game is supposed to be about having fun. If you're really serious about winning every game, then play with a party. This dude looks like he's having fun.
