This is why the community accuses you of not listening Riot

Because you don't. The community has overwhelmingly said Vel Koz is fine and you should not touch him. There are dozens of other champions that need more work that you could be working on. Instead you do your usual down talking to the players, using words and phrases like "feelings" "we hear you but". That really doesn't endear you to us, and your habit of changing champs, then leaving them hanging for long periods of time, hasn't really inspired a lot of trust either.
