I always run with Ghost, as I find it the most superior perk of tier 1 at least for SMG and AR and Sniper Rifle users. Really gives you an advantage, as I am one of those "bitches who camps".
I play mostly HC Demolition, and I camp 75% of the time, either to defend a bomb site or to prevent enemy from getting to a bombsite we are bombing. Honestly, I have no idea what is bad about "camping". If you die to a camper on a single route, why can't you choose another? As I have said before, camping is a valid strategy, and no matter where you camp there is always at least one spot where you can be surprised and shot. And there are grenades, too.
Only thing I dislike is when people jump and shoot. They don't dive to prone, which I think is fine, but they jump and shoot in the air with those SMG's.
For the guy calling other than running head first into danger cowardly: what, are you stupid?
