Any game that's chaotic will require brain to process and function faster. CSjoe is simple, you have to know the same few lineups for years and that's it and the game never changes so the requirement for a newer approach isn't there. BR like Apex and Warzone needs a bit higher requirement in terms of what fight to take based on what guns you got and also positioning since the possibilities of positioning is endless.
Valorant on the other hand is a whole different thing, since the map changes are brought in sometimes and also how molly's work on different agents you have to think a lot about both timing your molly's or shock darts from different angles and not to mention you can even block some molly's with your own body. Mix with this the fact that ults can affect how you use your util also makes you think about positioning to use something (for ex. viper sometimes has to go far from the planting spot to throw molly, KJ ult can put you away from the site and set you up to rethink how you use util and time to hit with a retake and all the teleporting shit and verticality to get info or peeking angles makes valorant just too complex for new people at times and even sometimes at higher level of valorant.
One example is TL vs PRX where jingg was elevated on sage wall on the boxes in Pearl B site and how he killed someone and created chaos for attackers, despite that angle been known to the community, you never know if it'll be used or not and when and you cannot expect it.
