If the game is as bad as you all make it out to be stop playing it. I know its so crazy that you don't have to play a video game you don't like. You can always go back to mw 2 since it was the greatest and blah blah blah.
People will complain about anything and everything in a CoDgame that causes them to die. If you kill them from long range with a SNIPER, they'll say it's too overpowered and demand for it to be fixed, or complain that lag caused them to die.
