He was quite clear about saying how QS is the same as it was in MW2, I think this will be one area they will not 'nerf' and leave it alone so the OpTic crew and all their little pre-pubescent fans can carry on posting videos to Youtube about how elite they are after the 100th time of trying they finally manage the 720 quick scope off the top of a building.
They obviously know there is a target audience for this stuff and are fully embracing that community of players.
It doesn't make that much difference to me if I am honest, I do not think these QS are elite players, yes it's annoying getting killed by them, but it's even funnier when you can smash them into the ground time after time.
