Why do Riot balance their game around this forum?

It's just painfully apparent that the vast majority of users on here are just flat out bad at the game and don't have the faintest idea on how to balance it. People still unironically claim that Zed is busted. A guy who is outright dumpster tier in any elo above Platinum. People still bitch about Yasuo. Why is Riot so insistent on listening to players who suck at the game?
