The 1 thing that keeps getting on my nerves during multiplayer is the Melee Kills.
Why do people die quicker from a knife than they do from hot bullets???
The only way that a melee should kill someone instantly is if you come up behind someone a cut their throat.
Too often I have been shooting someone a they stab me a move on.
Infinity Ward needs to require you to stab someone 2 times to kill them.
It doesn't make sense that you can put 10 hours into upgrading your FAV weapon with all kinds of attachments and perks only to discover that a guys knife is still a better killer.
