For league of legends I can see how this can work, in fact I've used many similar tools to understand how a certain champion works.... for the other games tho - the ones that are faster - wouldn't an in-game agent (like a coach) with good suggestions work? For example, in Warzone, someone in-game could say, oh look you might have not noticed but there are enemies shooting there, either go on 3rd party or steer clear of the area.

but now I guess that's against TOS of most games, right? i.e. a voice that tells you what to do / how to do better next round. Now that would be something useful to learn faster!
