Overwatch requires way more aim than CS or valorant, what are you talking about?
Overwatch has ZERO movement acceleration, each character has different hitboxes, and each character has different speeds and mobility (climbing walls, double jump, dashes, flying)
FPS=First Person Shooter. PUBG is a Battle Royale but it is also an FPS. You are talking about CS and Valorant, which is Tactical Shooter, and even then I proved you wrong with Korea's presence in CS 1.6 and Sayaplayer in NA.
You are building a narrative in your head that doesn't exist.
