You know you can still play MW2 right?
As you can see, most people hate QS. I will say it isn't as bad as MW2, but it sucks.
Here's my opinion on it:
People like you think that sniping is some type of elite class and you are better than the avergare player. Unfortunately you need QS to get kills. By running around and taking quickshots. This is NOT what sniping is about. It is about finding a little hiding spot, finding an enemy, lining up that shot and killing them. This was how sniping was in the game prior to the patch. The good players were able to get kills this way. The bad players just made thread after thread whining about QS (you).
I've found that there are a few more snipers in the games now, which is good. I love finding that moron trying to QS and just walking up behind him and getting a nice headshot from pointblank. Oh and SMGs have no problem taking out snipers from very long distances as well. See ya!
