The game actually does favor camping a bit more.
I played a game on Chasm where are team was up 20 kills but we could find no one on the map. There was a 3m period where we increased about 5 kills and they got maybe 1-3. The only guy you could find was the one camping the subway stairs spawn for kills.
I think its more due to the fact that every assault riffle kills you with impunity at every range. Spending more then 6 bullets to kill someone is a thing of the past. Even then I can still get 3 kills and a dog kill out of a clip of the honey badger.
"This game separates people that have real skill and people that THINK they have real skill."
And therein lies the problem for some. They are quite used to having maps with lanes that basically are enclosed pathways with short lines of sight and only one or two at the most vantage points to check. On those maps they could run full steam ahead because there was very little adjustment to be made to prepare for a gunfight. Now playing on maps with long lines of sight, they struggle to adapt. The truth of the matter is that every one of these maps have short lines of sight routes but not everyone has the good sense to take them when using a short ranged weapon. Heck even Stonehaven has a lot of opportunities for a guy that wants to push the middle. You just have to be aware of where the snipers are going to post up and keep your head down.
