want to know the last answer we had from riot about Aatrox?

Morello: We made some big game health mistakes on Aatrox that put him in a problematic spot there's accuracy in the fact that if he's buffed, he'll be a problem.

We've had some Aatrox changes to solve this (as a soft rework sorta thing) that could fix this, and then let him get back into the game. I'll have to check on the details to see which direction we've taken with it (there were a lot of ideas on the table for it, originally).

Not only it never happened, but you can see clearly here an issue that riot didn't solve

releasing champions with terrible kits, somehow letting go into live and then "we made a mistake guys, we can't do anything about this champ you have to wait"
