Quickscoping since Golden eye has worked the way I explained it, the nerf your talking about will only effect quickscoping in the sense of not pulling the scope in all the way and firing. Quickscoping is still when you quick aim and see the scope for at least 1 second and fire. And it is extremely easy to do especially on Call of Duty. Many other games have quickscoping but not the animations that CoD has, they are also more difficult to do effectively. Call of duty is probably the easiest game to quickscope on, literally takes no skill at all.
You obviously don't know much about quickscoping if you believe only half way aiming-in is quickscoping. What your talking about is pretty much noscoping. No-scoping isn't just firing from the hip, it is also when you click the left trigger (Or right based on your control setup) and the animation of aiming starts but you fire before you even get to see the scope or sight; IW is making it so that method isn't as effective as it is now. There really is no difference between quick-aiming and quickscoping, other than quick-aiming refers to any weapon and quickscoping refers to weapons that have scopes (Mainly rifle scopes).
