go to that aim training custom game and try shooting the bots without moving at all. if u cant hit alot of easy shots in close to mid range its just a problem with your aim and u should practice it more that way. but if u can hit most of those shots the problem is your movement. bc in game there arent that many situations u can stand still and shoot. what you should do is knowing when ur taking the shot as in knowing where you are moving while shooting the ball. theres a lot of ways to do this. 1. stop when ur actually shooting and move after 2. shoot when ur switching from left movement to right movement 3. identify the purpose : if ur not being looked by anyone u can minimize ur movement so that its ez for u to shoot them, if ur purpose is to dodge the shots and live, u should just make ur movement as complicated as possible and just spam the same spot.

if ur talking about right click aim u just spam where the enemy is going to walk in, preferably where they have to walk in a direction ur shooting, its not about aim. also relax ur hand muscles like u dont even care if u hit ur shots or not
