Things like playing the game is almost exclusively learned from watching others or reading guides that are nothing to do with riot's own input. Playing the actual game (They tried to keep new players up to date with a new tutorial, but this was last updated years ago and seem to have given up) Occasional hidden changes to a champion's ability TFT, there seems to be a lack of information on the full mechanics of the gamemode, like item recipes (like you said) Skins, the only viable way of being able to preview skins, is via SkinSpotlight's youtube channel This is something that Riot consistently never do, and that is never providing much information around their content and always leaving it up to the playerbase to provide these details.
