The Loot System Works
Because it requires the masses to be stupid, ignorant, and carefree. If they don't profit from the system, they will rid of it.
If you don't like the system, at least 80% or the playerbase needs to not pay for it. Pay for the system, and it won't go anywhere
Constructive criticism doesn't apply to business. You can hate it all you want, it won't go anywhere if it is turning a profit.
This is what Riot has turned the game into. Deal with it. It's a profit meta game that copies every other MOBA.
