Aatrox ult suggestion

As we know, Aatrox ult is pretty lack luster,

I was thinking and maybe it would be alot less underwhelming if you made his ult deal some sort of aoe life drain effect (sort of like a weaker version of swain).

i kind of imagine it like you dive in with q, activate your r and it starts sucking the life(or hp) out of whomever is closest to aatrox. I think this would fit aatrox way more thematically then his current aoe effect on his ult. You could also make it scale with ap(just as his r does now)

I remember that aatrox discussion a while back saying how aatrox was a sort of life steal tank and i think this would fit him more or even make him slightly more viable again.

Thoughts?
