camping = noobie
I am sorry but 99 percent of the players on this game (the campers that is) do it to have a high KDR. Some might say you do it as a tactic, but honestly most of the ones i hear that say that, do it because of KDR.
I dont camp and i already have 2.57 KDR, and last night i ranked 750 in kills, if you dont camp you rank up faster and have better stats, as well as you get to unlock gun attachments much faster.
When i play campers, simple, i use a WA2000 with thermal and heart beat sensor, i see if anyone camps with me holding that.
