And to be completely honest, it doesn't seem like a well thought out addition to the game.
Everyone cloaks promoting camping, and just making it very difficult to locate someone and slowing down the gameplay. Armor mode is useless. Hit detection is really bad because I've unloaded entire magazines into an enemy, followed by a few melees, only to be melee once and shot a few times and all my shots are hitting them, because many times I've run into camping targets. Having to walk over your dead target's corpse to get a dog tag to earn a killstreak is pretty lame, making anyone completely vulnerable, and the lag is pretty bad.
I'm not raging, just constructively posting the many faults I've run into. If anyone knows if the devs announced any patches for anything, please post or send a message. Thanks.
