Just explaining the fundamentals of aiming. I am just your average platinum player. I made this video so this can serve as a reminder to myself.
Diamond players and upwards often use more advanced moves to throw aims off. Such as A-D Crouch Spam or reversing jump direction in mid-air or DSPStanky Style aura juggling etc. But judging from footage of top streamers, even skilled players sometimes forget those fancy moves and spam jumps in the heat of battle.
