Ever played CoD? I understand it's difficult to satisfy all of the types of players but in all of the CoD games there's some sort of unbalance present.
I think the perfect CoD would be MW2 with its weapon balance combined with the perk system and everything (including maps) else of Black Ops. In MW2 there were only a couple of guns that were unusable just cause they were shit, in Black Ops there's about 5 guns you can use effectively (not to say you can't do well with the other guns of course) and the rest were crap (example: mini uzi).
