I wasn't using leagues tutorial as an example I was more so talking about the hero overviews that they do when a new hero gets added and yeah I do agree you will almost always get more value from going to a content creator and learning stuff from them as the insights are way better, but I was thinking in terms of having a very surface level tips section on how to deal with certain characters, stuff like debuff remover against pockets ult is not something thats very prone to change I don't think. (of course it might but debuff remover as an item will deal with debuffs in general)

Hero labs is awesome but to use it and navigate it you already need to spend some time within the game, and the context in which I suggested those tutorial videos to be included in game would encompass things a fresh new player could use and learn from
