I love seeing those kids that use AK74 Rapid fire with ghost and they get a high score thinking they've got skill. That gun is a short-distance, medium-distance hands down kill if you go face to face. No gun can overpower it. I've even seen some BS long range kills too. any time I come across a player that uses it, I bring up the xbox menu/recent players/find that player/leave feedback/avoid player/player skill/lacking skill.
It's annoying. "But it's legal," well that doesn't mean you're any less of a vaj for using it.
