Aatrox's Ult is a problem in pro play, why not remove it?
Change Aatrox's ult to be similar to his old w. Which would grant extra healing or damage (at a cost on your abilites, as well with every third auto) with e passive healing removed. Which could be toggled in between price and thirst.
Blood-price his abilities would cost more health and have the soft spot on the outside (like it is now).
Blood-thirst could shift the soft spot to the inside/have different shapes altogether, heal you, and only slow enemies close to you (More healing lower your hp)
Aatrox will resemble his old fighter more and will have much less presence in pro play
