The difficulty curve in the game has... problems...

You vastly overestimate my ability to translate "you know where you stopped casting in order to move because you can't mouse-turn and click a cooldown at the same time, don't do that." and "you know when you stopped casting in order to process information to not wipe everyone, don't do that either" into an actual increase in performance.

Wack a dummy and move around while doing it. MCH is the best for being mobile and maintaining up time. Do your rotation enough you won't have to think about it at all itll just be muscle memory. Also practice not clicking skills and try to adjust your keybinds where you can actively press all your skills with one hand and little movement. Good keybinds are very key, I can't really give you advice on that really mine many would consider bad but its comfortable for me. May want to look up some guides on keybinding and play around with it. It took me a couple hours to figure out how I wanted mine, and that is excluding practicing it afterwards and making adjustments.

For example I have my rotation as qwe, with my ogcds gause barrel and ricochet as 12, so I can easily press 12 after each step of my rotation, Drill air anchor and chainsaw I have as rty.
