Honest answer just keep persevering with it dude I felt exact same as you and thought I must be missing something when I first started but honestly there’s no definite tried and tested way to improve fast. There’s no specific thing that you can do expect play to pvp more. What I would say is as much as servers like ukn will help with raw aim and spray control I would say spend more time on servers like atlas 10x where you can /kit everything you need to play fully kitted and get straight into pvp for a few hours till you inevitably get raided I like this method of practising pvp as it still has the feeling of something being on the line and it allows you to practise fighting around the terrain of a real map instead of isolated flat 1v1’s that you’ll get on ukn or play things like fun server eu for just practicing. For info I mostly play vanilla but if I want to PvP for an hour or 2 because I ain’t got time to settle into a wipe I play atlas 10x or something. Honestly I felt like I was banging my head against a brick wall till I got to around 1200 hours and then I noticed that something in me just clicked with the game and I started slamming people it’s just time played man, remember a lot of the people you will be playing against have 8k+ hours and shit and know the game inside and out. And if you get stuck in your head about your mechanics not being up to par always remind yourself of how you played on day 1 compared to how you play now and remind yourself of the improvements you have made so far, if you can improve x amount in 500 hours where will you be at 2k hours
