I disagree because a true "ghost" class should remain just that... a "ghost" UAV jammer was much less of an option in COD4 because of the dominance of stopping power. They made Cold BLooded a viable choice in MW2 now because of the added benefit of anti-thermal and invisibility from air support. This also leads into the fact that the developers wanted a "counter" for the air support. Hence the ability to freely shoot them down with stingers when cold blooded is on. Think about it dude, yeah you get invisibilty from air support anti thermal and uav jammer but your also taking one more bullet to kill everyone else (assuming alot of people are using stopping power and sometimes lightweight etc) which makes much more of a difference then you might think alot of the time.
