Yeah, for me at least I tend to get a lot of deaths when going for the objective, I'm a objective player so I will always try and get it even if I'm the only one trying, the problem is this requires the whole team to participate, if not what happens is I get to the objective and Die.
I'm even using the RPG a lot less now, I actually get more deaths than kills with that fucking thing in BO2. Its very hit and miss, sometimes it takes 1 rpg to kill someone other times you fire 2 at the person dead on and they laugh at you.
I'm not too bothered about my KD tbh, I play for fun and the objective.
Will take a look at that video later.
