I have to say I hate quickscopers... They tend to use the sniper rifle like a super-powered shotgun. In fact it should be limited to a slow focus on the target like a real gun scope and if you use it under a minimum distance of the optics then the gun should be incredibly inaccurate. Some players would say "but this is a game" and I would reply "if you want to quickscope, just get a good shotgun instead". Quickscoping is just misusing the tools in the game. It's not skill, it's cheating.
