Well, to me, if I get killed by a guy camping in a corner and a few minutes later I'm approaching that corner again, I sure as **** ain't gonna just run by it. I'll probably toss a stun in the corner and spray it down just to be safe.
And it's been a month since this game came out. If you play it with any kind of regularity, you should pretty much know all the camping spots that people like to use and not be dumb enough to just run by them. Especially if you play any game type with a killcam.
