The problem is you can't patch the community, and people will only pay attention to the things they want to force themselves to pay attention to exclusively, and what people will pay attention to is actually far less than they claim. If you have a Yasuo main who says they only ever play Yasuo, they don't actually know his full list of strengths and weaknesses, nor do they consider how to approach different situations, or how to build in reaction to the threats at hand. I can guarantee you that 99.4% of all Yasuo mains, and by extension every other player, will build according to something predetermined, potentially not even their own decision, and not based on whether the enemy team is mage or tank heavy, for example. Hell, it's a trial to get anyone to even build Grevious Wounds, even if Soraka is on the enemy team and everyone won't shut the hell up about how much she heals.
That's the level of extreme binary thinking we have to walk back, and there are forces determined to perpetuate that mentality.
