Aatrox’s E needs to be a Quick Cast ability
As in the same line of Yasuo’s Q or Karthus’ Q, as in they don’t need a confirmation click. For a move that’s supposed to be used in the middle of a fight to repostition yourself to land your Q, it’s very disorienting and clunky for it to require a confirmation click which then could cause you to delay the dash, missing the Q.
I think this would fix one of his major problems of feeling clunky and would make him a bit more fluid in playstyle.
