Honestly the nail in the coffin for me is that his early game is horrible compared to now, and instead he is a late game scaler. Reworks are meant to keep elements of the core character, but they gutted his sustained combat with long CD's, made him want to stand far away from the enemy instead of right next to them, gutted his healing, pushed him completely away from being an AS oriented champ, replaced his amazing voice with something that I can barely understand the words of, and finally completely pushed him out of his niche as a strong early game champ who snowballs or falls off hard for something that is completely the opposite.
There is nothing about the new Aatrox that (as a fairly frequent Aatrox player) that makes me want to transition into playing him. I see nothing about old Aatrox that I enjoyed in the new Aatrox, and I am left wondering why I would even want to play the new Aatrox as an old Aatrox player. Katarina honestly feels closer to old Aatrox than the new one does, which is why I feel like this rework failed so hard.
