Ideas toward Aatrox rework/gameplay update

Saying this now, I'm no way creative enough to be on Riot's level for champion design, but am willing to throw in an idea and who knows. Maybe some rioter will find this and get some inspiration from me. Numbers can of course be changed, it's the idea that matters.

Looking at Aatrox as a demonic warrior and with the animated splash art having blood draining into his sword gave me an idea. Maybe having a increasing attack speed as he auto's a champ would support his duelist playstyle. Maybe gaining .10 attack speed per auto against the same champion (maxing at 10 attacks (+1.0 attack speed)) could support the bloodthirsty battle style. but him switching his target from say a tank to adc will reset his passive. This is slightly different from Jinx's minigun scaling attack speed passive, but seems unqiue to fit his character.

Seeing as Kayn's darkin resides in the scythe makes me think maybe his weapon should have a unqiue playset revolving around him fighting with it. Possibly as a basic ability he should be able to throw his weapon like a javelin could be a simple idea, but hitting a champ could pull him to that champ. He could choose to throw it just as poke, but have a second cast of it (like urgot ult) to dash to the hit target giving him a gap closer.

I do believe his w should stay the same with 3rd auto dealing extra damage or healing him is already ideal for his playstyle. You could choose to fight him as an assassin for extra damage, or sustain all-in'er. I do realize this is sounding like Kayn's two forms but I'm trying to replicate what a darkin would be like. High damage or a fighter.

Kind of out of ideas, but thought maybe I should share and maybe someone can add on to this or maybe discuss why something is or isn't a good idea.
