CoD is still Peer to Peer... =P
Although most if not all Shooters I would say are broken when they are released or new dlc is released as weapons that are new haven't been tested too much or the Developers feed off people's hatred, fear and anger by adding in weapons that are grossly overpowered like when the Famas appeared in Battlefield 3 or UMP-45 in Modern Warfare two which is used with Stopping Power became a one shot if you had stopping power and FMJ on as you could shoot through walls and if it was a headshot you'd get an instant kill... Haven't actually noticed any weapon on AW which is truly overpowered. Might be I am too amazed CoD has changed from a simple run and shoot to a simple run and shoot with jump abilities. Also has a nice amount of customisation for your character so it is unlikely to find people who are identical unless its a clan wanting to be in a uniform or something.
Hopefully Eternal Crusade is worked out so say someone used a certain bolter it isn't overpowered allowing you to blow through power armour in a couple of shots but needing to smash several round into the chest to even smash it open.
