Don't stop to shoot on distances lower than 25-30m and cripple yourself. We've been through this. This is not CS. Phantom is better, but Vandal works amazingly good as well. Run and try to get tracers as close to neck/head area as you can. If they live long enough to hit you while you are zooming around, you slow down to walking speed and become insanely more accurate and headshot them in the next 3-4 bullets (walking and shooting always was amazing in this game and still is). If they headshot you while you're running, well, they win the duel. Below 110k in AimLab ranks, this is definitely the way. Try it in few DMs, and if you really dislike it, don't do it.

I know that it feels reliable and like you're in control when you stop and shoot, but odds are skewed in runners favor on 0-20m distances and it's not really rng.

I wish i could put /s on the end of this post and that things I wrote were random, isolated incidents, but I can't and they're not.
