You're not going to convince Riot by calling it a problem though, you have to convince them that it's actively detrimental and demonstrate a superior alternative.
imo they pretty much have to remake the game from the ground up before anyone hyper competitive is satisfied simply because everything from the item selection to the core mechanics has been taking out or actively limiting player involvement.
