the thing you called "skill ceiling" in cs:go is the consiquanses of an old boomer things in an old engine.
Valorant has almost the same mechanics with the new engine and modern game. Boomer people are blaiming Valorant and say its low skill ceiling game and easier, because of the simple fact that in Valorant bullets accuracy is much better than in cs:go, so if you are aiming on head it will hit the head (first 3 bullets on rifle).
On an another hand, in cs:go with all the 12 yrs old mechanics - you literarly can't aim your crosshair on head and hit the shot like in Valorant, because even the pro players doesn't fukin know where these volvo bulets go (no tracers available). All what cs:go has instead - is the spray patterns which make the game the crouch spraying simulator: to enable to kill the opponent with rifle you need to crouch spray (because these fukin bullets goes whereever but not on the crosshair). You can watch one clip on S1mple's clutch against Astralis few month ago on Inferno: he was half HP, he had an AK vs two opponents, he was holding B site as CT, and what S1mple did? Yeah true, he swapt on Deagle and killed them by two headshots, he knew he would never do this with AK because he would need the spray (he was low hp) and lack of rifle accuracy.
In Valorant you have first 3 bullets accuracy, so this game just gives you more opportunity if you are good at aiming. Better aimer better chances to win the battle. Movement, positioning, macro strategies and utility usage (utility usage is actually hareder in Valorant, which we can call as the skill ceiling) is like in cs:go. The main difference is Valorant > cs:go in the way of aiming and shooting. Beacuse its a new modern game. Closed.
This is the reason why such bot like floppy aka rikky kemery would never be top tier in Valorant - he just can't aim clean at the tier 1 level. This is the reason why tons of tier 2 cs:go players from CIS (which i personally know few) - play worse than those tier 3 or even 4 cs:go players, in Valorant they became better because game fits their style and fits their AIM style. Thats why T0nz is still tier 1 in Valorant despite hes bad in game sense. Thats why Brehze or Elige, if they will switch, will dominate whole NA scene - Elige and Brehze are briliant aimers (besides their good game sense as well) and Valorant fits them even better than cs:go. Thats why (very hot take but i think its true) S1mple would never be top1 by vlr.gg/hltv in Valorant - i personaly think Valorant doesnt fits him, he needs true awp mechanics, people will counter his operator with abilities easy and etc.
The last thing is about spray pattern in Valo. I remember the reasons from rito officials why the will not implement a full spray patterns: its because they want Valorant be more precise aimwise, taps and bursting. if you need a spary pattern it exists for 10-14 first bullets at rifles, not for all mag.
