Aatrox Rework concept

Aatrox is clearly in need of some sort of rework. His kit makes no sense thematically and I think this little thing I whipped up in like 10 minutes (Hence lack of any damage numbers) So I thought I would take a small approach at making him feel more themed around the using blood concept.

So in this version, he uses blood well for his resource instead of his health. Blades of Torment is the only unchanged spell.

Feedback would be appreciated, it's pretty rough around the edges but I would just like to know what you guys think of my idea.

PASSIVE: Blood Well

Aatrox obtains and stores the blood of his enemies whenever he autoattacks a champion, minion, or monster. Aatrox gains bonus attack speed based on how much blood he has. If Aatrox leaves combat for a few seconds he will begin to lose blood, slowly at first and ramps up quickly. (Well can hold 200 Blood)

Upon taking fatal damage, Aatrox enters Stasis and drains his Blood Well, healing himself over the next 3 seconds for up to 35% of the Blood Well's maximum capacity, plus its stored health upon activation.

Q: Dark Flight COST: 50 - 100 Blood (Depending on range used at) COOLDOWN: 22 / 20 / 18 / 15 / 13 Active: Aatrox dashes to the target area after a brief delay, dealing physical damage to nearby enemies upon landing and knocking up enemies in the epicenter for 1 second. Dark Flights RANGE may be increased by up to 500 units by spending extra blood. (Move cursor outside the normal cast range)

W: Blood Price/Blood Thirst COST: 10/12/14/16/18 Blood per auto attack COOLDOWN: 0.5 Seconds Passive: Aatrox applies a bonus on-hit effect every third auto-attack. Blood Price (TOGGLE OFF): Aatrox heals himself. This heal, along with the amount of blood gained in his blood well is doubled when he is below 50% HP. Blood Thirst (TOGGLE ON): Aatrox consumes part of his blood well to deal bonus physical damage, cleaving enemies for a portion of the damage around his target. Blood can not be obtained during Blood Thirst.

E: Blades of Torment COST: 30 Blood COOLDOWN: 12 / 11 / 10 / 9 / 8 Active: Aatrox unleashes two converging energy waves in the target direction, dealing magic damage to enemies hit and slowing them by 40%.

R: Massacre COST: 50 Blood COOLDOWN: 120 / 95 / 70 Active: Aatrox absorbs the blood of his surrounding foes, dealing a percent of their maximum HP as physical damage. Aatrox is healed and his blood well is filled depending on how many enemy champions he hits. For the next 8 seconds, Aatrox's attack speed bonus is doubled, his movement speed is increased by 30%, and his attack range is increased.
