So why not create a separate client for high ELO?
Riot makes a lot of bullshit changes so that LC$ stays interesting, while the rest of the playerbase suffers.
So why not just make a separate client for high ELO (like diamond+) that you can opt into, and balance it individually of the standard client? If you're going to refuse to actually balance the game to keep tournaments profitable, then let the people who can even think about competing deal with it while everyone else gets a somewhat fair game.
