so braindead, lol. That is not what people are referring to when they say skill ceiling being low -- or at least, it shouldn't be.
Valorant has a lot of utility, which creates a huge amount of variables. That's what introduces elements of randomness to the game.
Think about all conventional sports -- football, basketball, rugby, baseball, hockey. They are all basic at the fundamental level, and so you have to fine-tune a small number of variables to extremely high levels in order to win + athleticism.
Simple games create high skill ceilings because you have to rinse and repeat a small number of things over and over for perfection. CS:GO is a more simplistic game, and therefore it requires absolute mastery to be good. It's not only about the hitboxes and shooting... That's one tiny element. The real difference is that Valorant has so many variables, which makes it harder to win consistently, and therefore harder to predict and harder to anticipate round to round.
