Thank you for the video, very nicely put together. I actually have the complete opposite opinion to yours :P To me winning a 1v1 or generally being good at crucible is determined by the time it takes a person to aim the gun at the head of the opponent from the moment they spot them. If you are quicker at aiming than your opponent is you will win the fight. The only way to practice aiming is by constantly playing. In your video, you land some top notch head shots with a sniper, you can't teach that to someone who is not landing head shots by just watching videos of them not landing head shots and thinking "well next time to fix my error i just gotta land that head shot" :P Not a lot of people talk about the sensitivity that they use when playing crucible and the fact that to be better you have to know the map and keep your aim where you expect your opponent's head to be.
