Nr 3 definitely 3!!! I can't tell you how frustrated I am about that! As a HC user I feel it's hard enough to play pvp, but as I sometimes empty a full mag into someone right in front of me and they just won't die is so frustrating! I'm happy to hear it's a problem other people have too, I wasn't sure if it's me or the game. But then again, I play the game long enough to know when a bullet is hitting its target and when it doesn't... But it's all messed up now...
