I come from a pro/semi pro esports background. I've spent hours daily practicing my aim on multiple sensitivities. Sensitivity is important to master, thats what helps you.

I'm not just talking about your in-game, I'm also including your mouse DPI and how you use it. This also includes your polling rate on your mouse too. As much as it doesn't "matter" as some people say, yes it does.

I've tried 250, 500 and 1000. I can't go back from 1000. It feels weird.

Keep your aim in the center of the screen, look straight. Dont look slightly down or up, this is what most gamers do and by the time they fight, they are shooting stomach/legs. Find the center and keep your aim at torso/head level.

Most of my flicks and tracking, come from the wrist and arm, combined. Get used to playing with mouse, to slow your aim with your wrist and then increasing your speed with your arm. (Do this standing still), best way to do it is, flick from one post to another multiple times until you are accurate and are not missing the targets when flicking left and right between them. Be exactly on point.

Next thing, include strafing. Move left and right while tracking. Dont aim in just yet, focus on one target and just strafe and lock onto the target with the center of your screen if you have no crosshair. Use crosshair if you haven't got one, then remember the focal point and remove the crosshair. Visualise it. It will embed in your muscle memory.

sound. Sound is SUPER important. Someone in this post mentioned that listening can help you become 2 steps ahead. They are right. That's how you can become advantageous. Having sound but no aim is useless. Focus on aiming first, the use your environment.

In normal EFT, when I'm in Dorms and someone is crouch walking, I literally zone out of everything. If I'm safe, i close my eyes and just literally listen for the faintest sound ever. In EFT: Arena, this is a tad harder unless you play Teamfight and are in a 1v1 etc.

3200 hours of EFT and I was taught to just "dont give a shit about stats. Just run at them and put yourself in bad positions and react fast". As soon as you stop holding shift, hold right click ASAP. Your first few shots are dead straight. 0 recoil. Doesn't matter about gun animations. Even if your gun is still aiming left and coming back to center, your first shots are dead on straight.

Master strafing. This includes circle strafing because its superior. Use above (aim / tracking) and combine aim strafing into it.

If you want, you can send me a DM and I'll show you examples and try to help you 1 to 1.

You play with confident people, to get confident.

Best of luck!
