Aatrox Buff in 6.19 or 6.20?

I think Aatrox needs a buff in these upcoming patches because he is just very "ewww" and feels unrewarding for the effort you put in for him while every other champion is (easier/more reliable) to use and gives off the same or even better reward. If I want a initiation I would pick Zac over Aatrox, If I want sustain I would pick Vlad, If I wanted a fighter I could easily pick Irelia, Jax, and Trynd to do his job, and if I wanted a Tanky Damage Dealer I could pick Darius. All champions do his job easier and I think a small buff would really help him out.

And no I dont mean buff his damage because I already know everyone and their mother thinks he could become to "OP" with damage buffs (even though I dont see it making him op) BUT HERE IS MY IDEA AND I GOT GOOD REASONING FOR IT TOO!

**Why dont we buff his Q speed and have his knock up range be the whole circle? I mean if I am spending 10% of my health to cast the low range, small circle, small damage for a knock up that on a high cooldown, then I would hope for it to be reliable you know? **Could this buff make him balanced but have a reason to be picked? I mean the only reason I want this buff is so if someone plays aatrox I dont see the "Why would you play Aatrox out of everyone else?" I see this nonstop in my games when I play him, my teammates play him, or when my enemies rage at their aatrox. I want him to be a viable pick is all :(
