Be thankful that is all you have to deal with. The camping in this game is nowhere NEAR the amount of camping in COD. I just picked up BO2 yesterday and every map I have played on was EXTREMELY camper friendly despite the majority of the communities effort to convey the message of disdain of this to the developer.
So next time you want to complain about how someone knew you were coming because they had PV, just be thankful that is all you have to deal with. Because when it comes to the camping aspect, this is a cake walk compared to the crap you have to deal with in the new BO2.
