How would we feasibly improve the playerbase?

We all know that many of the game's "players" are far below acceptable quality. Talking about those 2:00 backcappers, the ones who steal jungle and the junglers who don't rotate back to jungle.

I'd think to improve the game maybe a revision of the ingame tutorials is needed? Like have advanced training that explains basic strategies like rotating, teamfights, when to farm. AND to make people actually want to do them, add a coin incentive. Thats how i'd do it, but I really want to hear more takes on this
