I don't think the issue is that you reworked Aatrox, but that his kit changed so much
Aatrox went from a champion who would jump in and auto attack to survive to a champion that presses Q, and auto attacks once to kill someone
The reworked Aatrox isn't Aatrox, it feels like an entirely different champion
I understand the need to change a champions kit if it is too toxic, but Aatrox's kit wasn't deserving of changes like this
