So untrue it's ridiculous. You do realize a headshot will kill pretty much no matter what regardless of mode, especially with the gun you put down. The problem with HC isn't that people die when you shoot them in the face, the problem is people die when you shoot them in the FOOT.
Nope, sorry. I wouldn't just come out and say something like that unfounded.
Try what I tried. You and a friend join a low-pinging, empty server. One of you stand in front of the other, and allow him to shoot you in the face with an AK - no juggernaut or damage perks. Same with a desert eagle. No death. That, to me, stinks of shit. A game mode that allows you to get hit in the face at arm's length with a .50 round and live sucks a fat one.
Besides, if you get shot in the foot or leg, you may well not die instantly but you'd be all fucked up.
