Aatrox Suggestion

So when I played Aatrox during this free week, I found that while he gets up to 200+ damage every auto attack and can burst down a squishy with a face roll combo ( Q his in the mid, E all over them, hit R and right click until damage proc on W), I found that after that burst, the enemy just sort of dashes away leaving you just sitting there with a raging blade angrily trying to right click the other target only to get systematically nuked by the squishy who got away.

And having only his Dark Flight to get in someone's face, his Blades of Torment not being spammable enough for a puedo perma-slow and just the fact that he's melee and is based arought right clicking people to death, he seems to lack the Xin Zhao or Master Yi level of stickiness these champs have that makes carries poop themselves when they go ham.

So, since he was described by the team who made him as a graceful fighter, what if he didn't need to stop to auto attack when he uses Massacre? Like, it seems that the reason he stops when not using it is because he apparently swings it with all his might for every cut/cleave/stab and needs to brace himself on the ground, so when he does go full flying demon on you with an even bigger sword, it seems that he should have no problem just hacking people to bits while flying around. Thoughts?

TL;DR: Aatrox isn't sticky enough to be a threat to carries past his initial burst, so I thought it'd make sense thematically if he could move while auto attacking during his ultimate, Massacre.
