tapping is still legitimate, and spraying is only effective if you have control of the recoil. However it's when you choose to tap and spray that makes the real difference, but most people still think an enemy 100m away behind a chest height box is an acceptable situation to spray in.
Due to the built in variance of bullet placement (spread), you could have aimbot level spray control and still only hit a couple of shots at great range.
I'm really not impressed by that shroud video. Looked like total lack of control, and the five-seven at the end? Would look at home in a silver game the way the T's fumbled that site entry. They were 5v1 and with bomb, as soon as they realised where shroud was, they should've taken B. the awper with like 1hp runs into a crossfire, the guy blocking his teammate in the doorway DUCKING no less.
Call me cynical, but I think very few frag videos show skill more than a total fumble from the opposing team (ie: 1v1v1v1v1v1 situation).
