MW2 is inherently unbalanced in regards to perks. There's no way to counter Stopping Power or Danger Close without getting the Painkiller Deathstreak, which is also unbalanced. One Man Army, Commando...the list goes on. MW2's perks (and deathstreaks) were adventurous and different, but made the gameplay more perk-centric rather than gunplay-centric, and without proper ways to counter perks, certain perk combos could ruin the flow of a game - especially when multiple people use them (evidenced by OMA+Danger Close+ GLs or Marathon+Lightweight+Commando+Tac Knife).
