Turrets, Cannons and the Balance Team

I'm generally not one to hammer down on the incompetence of others, but god what is the balance team doing? The community has been complaining for months that turrets are absolutely useless and do nothing in the game. Riot comes with a Baron buff and this is the result: https://clips.twitch.tv/VibrantPunchyDolphinYouWHY https://clips.twitch.tv/MoldyFrailStrawberryBCWarrior

Why do we even still have turrets at this point? They may as well just disappear when you hit the 15 minute mark.

This is not the first time they have done the absolute opposite of what the community expects. On top of that the balance team doesn't seem to have any capacity to predict the effects of their changes. In season 7 we got massive increases to the shields in the game, and the community warned of the negative effects this would bring, multiple times. The balance team decided to once again discard the concerns of the community; and here we are, one year later, and the balance team admits they made a mistake and looking to cut back on shields.

This seems to be a repeating occurrence, and the balance team doesn't even seem to care. I already know what the response to the baron buff is going to be (in a very casual tone): "Yea, we did miss the mark with this one and it didn't turn out how we planned. We'll be looking to diminish the effects of the Baron buff and ways to buff turrets."

If I repeatedly waste everyone's time and money at work, I will be held responsible and will be in deep shit, especially if I ignore multiple warnings that what I'm doing is not effective. I get the feeling Riot's balance team isn't held accountable as much as they should, otherwise their capacity to learn wouldn't be as bad as it is.
