Also the weapons aren't the balancing issue. The inbalance is between skill levels. Some weapons are more powerful in a given situation than others but anybody who constantly thinks they're are only dying because the opponent's weapon was more powerful is probably bad.
Do all you crybabies who bitch about the knife not use it yourself? Commando lunging is gone. Getting knifed through your bullets is annoying yet if you're close enough to get knifed, you're probably close enough to knife. Random genades killing you is way more annoying anyway.
What game have you been playing? Just type in commando lunge mw3 in youtube and you see thousands of videos proving that its still here and as rampant as ever.
