How the fuck do some players have some kind of armour?! I'm shooting them for AGES, they turn and shoot me once or twice and it's over? I know I'm hitting them, my aim doesn't move off their body! And yes my weapon does have good power!
Secondly, anyone else noticed when you go around a corner and see an enemy that you can shoot straight away, but when he kills you (because you've been shooting him for ages and not killing him, see point one) and you look through the KillCam, you see he came around the corner and seen you for a lot longer, at least a second before he starts shooting? But I see him straight away and I'm firing away. Very strange.
