Totally agree here. Second chance is craptacular. I was playing last night with the crappy Olympia. Every second player I came across seemed to have second chance. I pump two shots into the body and get killed while he's in second chance and I'm trying to change weapons. As much a fault of the weak shotties.
RC's are insane. Got sick of using them myself and felt cheap. Last night it seemed like every second our team or the opposition was unleashing an RC. My friend and I were actually laughing about the constant announcements. Should have been at least a 4 kill streak if not 5.
I agree with the RC's. The problem is that it's a 3 killstreak (2 with hardline). They should have either made it to be air dropped like a care package or made the killstreak as 5 or 6 instead.
I personally haven't had much problems with second chance. But I hardly use the shotgun. Most times I can tell they are not going to die straight away and put in a few bullets before they get a shot off.
