Let us buy items with gold

Good idea because it also gives Riot an easily accessible stat to balance items. Everyone is buying Shojin? Nerf.

That would indicate that you think you lose more than not because of an item deficiency. People with chronic item deficiencies who have higher win rates than they should, since items determine all games it seems, are also out there saying items aren't a problem. And your fix would likely be a break since it'd give reason for the game to be an all-gold meta over others.
