I've sunk 3.5k hours into MOBAs such as dota or league, mainly the former, so I can attest to the fact that playing tons and tons of matches definitely will help you know what to do in different (but similar) situations. However, I also know many people who for example may have 5k hours in a game and be stuck in herald (equivalent of iron). I feel much like MOBAs, while you can play tons of matches to learn what to do in each situation, sometimes you'll learn and maintain poor habits. In valorant, positioning and game sense is something that I hope to improve. By game sense, I mean everything unrelated to mechanical skill.
