(Custom Rework) Aatrox, the Darkin Blade

So after some reminders how poorly designed Aatrox kit is in comparison to his theme I've been working on a this project of mine. His current kit is basically some very generic fighter stuff wheras his theme holds so much more promise. Like he's this being whose mere presence can turn the tide of battle by turning an army or a group of broken morale into a bloodthirsty horde whose only focus is claiming victory. Something that is definitely not exemplified in his current kit. There is really nothing which shows the effect he has on the tide of a battle. Hence I've worked a bit on a custom rework for his kit. This custom rework of mine really changes him as he is now, in fact you could almost call him an entirely new champion, similarily to how Sion and Poppy could be considered new champions. His kit as I've imagined it is something which I tentatively call an utility fighter.

So I'm just gonna drop this here for some feedback. Do note I intentionally keep numbers out of these early design stages as my focus is on what I want a champion to do not how strong that is supposed to be.

Removed: Health cost on abilities Added resource: Fury

Passive: Bloodfury Dealing damage or taking damage will generate fury. For every point of fury Aatrox will gain X% bonus attackspeed. Once he has gained at least 50% of his max fury his bonus will bleed off to nearby allies granting them half of his bonus attackspeed. Aatrox max fury is Y + Z(per level)

Q: Dark Surge Aatrox surges forward into target direction, damaging and slowing all targets hit for X + Y% AD (physical damage) and generates Z fury for each champion and 1/2 Z for each minion struck.

W: Living Weapon Passive: Abaddon Abbadon, Aatrox's living weapon, stores destruction charges based on X% of his damage dealt.

Active: Wanton Destruction Aatrox infuses a target allied champion or self with Abaddon's power of destruction. Target champions basic attacks are split in X with each attack dealing Y% of the original damage. (Additional basic attacks can crit as regular and apply on-hit effects [both at the Y% reduced rate]) If Aatrox targets himself he will gain Z bonus attack range.

E: --- (no name yet) Aatrox deals X + Y% AD physical damage in an area around him. Z% of the damage is converted into a shield. Minion generate only A*Z% shield.

R: Furious presence (tentative name) Aatrox begins draining his fury and creates a zone of fury around him which moves alongside him. The bonus attackspeed granted to allies while in this zone is doubled. Additionally when allies fall under a threshold of X% max HP they are imbued with additional power in a last ditch effort to gain victory. Allies will gain X% AD, Y% AP, Z% LS, A% SV
