how to improve aim

whenever I get into high dia-low ascendant lobbies I get shit on in the majority of aim duels I take. I'd say my game sense is very good, I can basically tell where the enemies are gonna be the majority of the time and take advantageous duels

a bit of background information:
the agents I play are omen, astra, jett, raze, clove, sova, fade, gekko, cypher, skye (I am also decent at some other characters like viper, phoenix etc but I don't play them a lot)
I'm generally better on controller/sentinel, duelist is on and off while initiator I tend to have a lot of bad games. I can get a lot of impact by lurking in some games on controller/sentinel but depending on the enemy team's comp and how my team is playing (may just w key and all die in 2 seconds) I can't do much by lurking 🗿.

anyway I'd like some advice on aim training and how useful it actually is from people who were in a similar situation

send a DM vod if you can
I posted one and a lot of people helped
also to me (someone who's also floating around high dia/low asc) it looks like you're playing waaaaay to many agents

valorant is mostly microflicks since most duels will be ideally close to your crosshair placement

To improve at microflicking do a lot of precise tracking scenarios--the little adjustments you tend to do when tracking a target will eventually become smaller and smaller allowing you to also do smaller and faster microflicks. This is why a lot of overwatch players' skill transfers over

Tracking ---> Precise tracking ----> microflick scenarios will lead you to having good aim for most roles except for maybe duelist

If you want to have good aim as a duelist I recommend also doing a lot of wide flicking scenarios after you finish microflicks

Brother, im low radiant atm, gonna tell u one training that i do, that is waaay unusual, but will really helps and ppl sleep on...

• So, first, aim its really not that necessary, i have friends that have a very strong game sense and are Radiants even higher than myself, but with worst aiming and mechanics. U just have to play properly, and by that, i mean, taking adventage of positioning, setups, and duels. If ppl are shiing on u, is bcuz u are not positioning that well, and u are allowing them to sht on you :D;
• Second, i did all the training drills that u can think of, Aimlabs, Kovacs, DM's, Range... I cant tell u wich is best, cuz u need to see that for yourself. Personally, Range for me, on 100 bots, without that strafe option, and practicing my A-D counter strafe. All i do is that.
• Third, the drill that i told is unusual, but helps me THE MOST, with aiming, game ideas and etc, is Swiftplay. Yes. Swiftplay. U will face every rank there, but thats not the important, u just HAVE TO play like it was a ranked, u dont need to call, or whatever, but focus on your gameplay. If u play as sentinel, try to lurk properly, train your setups, pay attention on the map... as duelist, go with your teammate, , and try to take duels, even if they suck...u can awp aswell... but i beg u, under no circumstances play as initiator, cuz that will require teammtes, and in swiftplay, ppl do what they wanna do.
• Fourth, last advice, be confident, if u are asc, u already know that confidence will massivly impact your gameplay, try to improve that. Like i said, aiming is not the most important.
  Take care, hope i could help, that took me a while, my english is terrible.

Have fun.
