So,

As from previous posts, I reached Radiant numerous times rn top 800 EU and I will explain to you how to get better without having dynamic aim (Aim Lab grinding etc).

Im avg 70k on Gridshot my record is 75k and I still outperform most of players I encounter in-game so those are detailed things you are able to get better at quicker than grinding aimlab for several months.

1. Gamesense, just think - Example (Split) A guy has planted the bomb on A side and was elbow last time, you faked defuse - mostly he will come around you and come from other side instead of elbow, dont look elbow fake it and wait for him to peek you if you have enough time(and to the opposite thing while being on Attackers side).
2. Economy knowledge - you lost pistol round and spike is planted? Buy Stinger/Spectre + shield enemies will probably buy only shield and utility / spectre + shield / stinger shield / 2.9k + light, and you can just run n gun with stinger doing double headshot and try to win a round, if you succeed you are getting free round, play full when all of ur team have enough for light+2.9k+utility especially if yours ult are stacked, dont be afraid of playing shorty/bucky/judge with no shield because if you will kill an enemy you will earn more than you lose if not at least you tried.
3. Crosshair placement and knowing how to peek- vector theory ( I tried to doing video myself but Im trash editor and it's mostly based on it), just watch some cs/valorant videos and implement it to your game it takes less than a week and your aim will go so much better even without having dynamic one trained you will find yourself in so much easier place than you were before. (I have it, like most good players on perfect or at least close to perfect level and that's why Im where I am with 70k on Aim Lab
4. Game knowledge - if you can't play a lot of mms (this is the place when you are getting this knowledge) just watch some videos which will help you understand where KJ turrets most popular places are where are Cypher's trapwires, where are good places to play as a Jett with Operator, where not to plant when Sova is in enemy etc.)
5. Be patient, you have whole round to plant a bomb which takes only 4 seconds, don't have to rush when there's 50 seconds to end, play contact and play as a team, hold defensive corners after plant and on def side.
6. Be unpredictable - if you are doing offensive angle more than twice you will get probably killed, push through smokes sometimes cuz enemies often dont expect it to happen, fake plant on 5 secs to end (its gamble and works only when you know where's enemy and DONT YOU DARE TO MAKE ANY STEP AFTER FAKING), do oneways,flashes, but dont do it every round cuz enemies will just find way around it.
7. Refrag - dont mind baiting as long as you are getting successfully refragged and you are playing as XYZ and you kill enemy topfragger, remember playing defensive corners is not the same as baiting - sometimes your teammates are trying to blame you but brush it off play your game and in some cases just mute them.
8. Know your main and secondary agent, dont instalock (especially when your rank is lowest cuz statistically as long as you are not smurf they are better than you), flex to your team and do the next step.
9. Dont be afraid of dodging, you will wait from 3mins to 15 mins for a dodge and it is better than getting 3 players w/o VC and 5 duelists (which works 10% of the time) or losing Elo and fucking up your MMR.
10. This will be an unpopular opinion but play solo/duo - you can blame "But mY tEaM hAvE CoMMs" I dont care you wont be able to do more than duo D3 and higher, learn to play the hard way so after D2 you will be able to survive without perfect info / inconsistent players who apparently will fuck up ur game(losers q is real)
11. Learn to play both weapons Phantom/Vandal cuz not everyone plays ur main
12. I dont belive I have to say it, dont give a fuck about skins, better weapon first, dont swap the weapons for skin because this Judge skin is pretty so I will swap my Spectre/Bulldog/2.9K Weapon on 3v3 situation - mostly it will be shitty idea and just gameplay before skins (at least on rankeds)
13. Dont be toxic while not being toxic - its weird to hear but peoples have this redline in brain (at least I have) while saying something you know this will piss somebody off, so yea don't tell "Guys on a can you dont die there?" - OH MY FRIEND HOW I COULDNT GET THAT IDEA MYSELF, just tell them do play defensive or just swap with them, don't tell them obv things you know they know and they know you know so you won't tilt (probably if you are getting flamed on in most of your matches, well it's probably not because community is toxic probably as well you are (not applied to women's playing this game because you are getting bullied because as long as you are not outperforming most of your team they have anchor point to flame you and it is your sex))

I think it is everything I can think now on, will do an update tomorrow, sorry for shitty English but Im not fluent speaker by any means
