UAV Jammer/Cold Blood Have always been my go-to perks in CoD because I usually play Hardcore, and there is no need for Stopping Power. But I have never heard of people being pissed about it. If anything, teammates would get frustrated at you for using it occasionally because of the no name tag thing and subsequent accidental team kills.
The only reason I would imagine people would have the same hatred for it now as they do second chance is the new perk combos. Ghost can be worn with different things now to change how it is played. Also, you get a ghillie suit. Personally, I don't care what perk a guy has, I care about what kind of weapon he has. A bush with a shotgun, SMG, or AR is not pleasant when I assume he is a sniper. I digress.
New people who have never played a CoD game are on Blops, so they have never played against ghost, jammer, or cold blood. They simply don't know how to play the game. That's all.
