One of the things quite some people disliked about Black Ops, was the removal of proper quick scoping. After many complaints from the “quick scoping community”, Treyarch decided to alter the way sniper rifles work and by doing this the quick scoping returned. Though you can quick scope in Black Ops, it is and never was the same as in the previous titles in which you could properly quick scope.
If you’re a quick scoper and you’re thinking about getting yourself a copy of Modern Warfare 3, I’ve got good news for you. Quick scoping will be back in Modern Warfare 3.
It has been confirmed by Robert Bowling that quick scoping will be back in Modern Warfare 3. Robert Bowling says:
"Currently, you can still quick scope in Modern Warfare 3. Keep in mind though, multiplayer is always changing at this stage (new perks, new balancing, new everything all the time based on feedback), however our philosophy on that hasn’t changed since MW2"I know this news will make some of you happy and some of you unhappy, but Infinity Ward choose to keep the quick scoping in the game. Whether you agree with it or not, at least you know what you’re up to now.
