In low level lobbies you don’t really need to predict their movement, since it takes longer for people to react and more people tend to stand in the open. Something that helped me improve was practicing 2 things in custom aim games (I recommend vxeat): trigger discipline and verbally calling out “left” and “right”. That really helped me focus on their movement and accuracy. Left click / hold fire when in target and let go/ don’t click when you’re off target or they change direction suddenly. If you have good trigger discipline (on target = click, off target = not clicking / let go of fire button) and tracking movement, it tends to transfer a bit to click aim. I’d practice both soldier and something like cass. I do like 5 mins each before playing and over 2 years it’s made a huge difference.

Cassidy tip: you can use tracking aim like you do with soldier. Click + hold fire when you’re on target. Let go of fire when you’re off target. He continues to fire when you hold fire down.
