An idea for Aatrox

When Riot slightly reworked , they gave Bio-Arcane Barage the ability to not only double his attack speed, but also his attack speed cap, making it to where he can hit 5 attacks per second.

I was wondering if a similar mechanic could apply to ? I don't play him (let alone, even own him), but I do know that he benefits GREATLY from attack speed. Since the removal of Zephyr was somewhat of an indirect nerf to him, and the fact that he has been needing some love recently, could this mechanic be a way to improve his gameplay?

For instance, lets say we put it into his ultimate (since it already gives attack speed), and for every unit/champion hit, he gets a percentage of attack speed, up to a cap of 5 attacks per second. I'm sure the animation crew would have to think up of something interesting for this, since he basically would be a blur when this goes on. Also, I don't think this mechanic should go anywhere else but his ult, since, normally, it would probably be WAY too powerful on him if he could access it on a regular basis like Kog can.

Thoughts?
