Whether its an exploit or not this is a good idea.

If you think it is you aiming and being a good shot you wouldnt mind aim assist off cause it wouldnt hurt you at all.

Well sniping normally isnt affected by aim assist.. The idea is when you scope in really quickly while pointing in the generally area of them the aim assist kicks in and makes your sniper bullet a one shot kill magnet.

If my assault rifle did that id agree.. but it doesnt :/

It shouldn't matter if it is there or not, quick scopers are the ones who use it most. The rest of us just kill them

I use ARs and not much else. I hate AA and have it off.

your really asking how its an exploit.  you know damn well how its an exploit. it exploiting aim assit.   if you cut aim assist off i guarantee you wouldnt be able to queerscope anywhere near as well as you do now.  its funny how the only people that dont consider the AA bug on QSing an exploit is people who QS.   On the PC version you dont see QSing, you know why?   NO AIM ASSIST
