[Champion Rework] Aatrox, the Darkin Blade

Just some things I'd like to see from the Aatrox rework.

P: Blood Well CD: 180/160/140/120

Passively, Aatrox fills his Blood Well through his abilities, depleting by 20% per second while out of combat. When the Blood Well is filled, Aatrox becomes Hellbent for 4 seconds as the Blood Well drains. While Hellbent, dealing or taking damage against enemy champions or neutral monsters will completely fill the Blood Well and refresh Hellbent's duration.

Hellbent: Aatrox gains empowered abilities and 30/40/50/60% bonus attack speed. Upon taking fatal damage Aatrox will revive over 3 seconds, recovering 30% of maximum health over the duration. Upon reviving, Aatrox instantly recovers 100% of Blood Well. Aatrox's revive is then put on a cooldown.

Q: Dark Flight Range: 650 CD: 13/12.5/12/11.5/11

Passively, using this ability fills Blood Well by 20%.

Actively, Aatrox dashes to target location, after a brief delay, dealing 10/35/60/95/120 + (100% AD) physical damage in a 225 unit AOE, and knocking up units within a 75 unit AOE. While Hellbent is active, this ability deals 5/12/19/26/33 + (15% AD) bonus physical damage, and grants Aatrox slow immunity for 1/1.5/2/2.5/3 seconds, if this ability hits an enemy champion.

W: Blood Price CD: 10/9/8/7/6

Passively, using this ability fills Blood Well by 10%. While this ability is on CD, basic attacking reduces the remaining CD by 0.5 seconds.

Actively, Aatrox empowers his next 3 basic attacks, at the cost of 30 health. Each attack deals 15/26/37/48/59 + (25% Bonus AD) bonus physical damage. If the first two attacks hit enemy champions, the damage of the third attack is doubled. This ability deals 50% damage to turrets. While Hellbent is active, Aatrox heals for 5/9/13/17/21% of the damage dealt by this ability.

E: Blades of Torment Range: 1000 CD: 12/11/10/9/8

Passively, using this ability fills Blood Well by 20%.

Actively, at the cost of 30 health, Aatrox fires two converging blades in the target direction. The blades deal 65/115/145/185/225 + (70% bonus AD) to all enemy units they pass through, and slows them by 20/25/30/35/40% for 2 seconds. While Hellbent is active, Aatrox gains 15/15/20/20/25% bonus MS and 15/20/25/30/35% attack speed for 2 seconds, after casting this ability.

R: Massacre Range: 550 CD: 100/85/70

Passively, hitting an enemy with this ability fills Blood Well by 20%.

Actively, Aatrox deals 150/200/250 + (80% AD) in a cone in front of him. Enemy champions hit by this ability bleed for 20/25/30 + (15% AD) physical damage, every half-second, for 3 seconds. Aatrox heals for 25% dealt by the bleed, reduced by 30% for every enemy champion after the first. While Hellbent is active, Aatrox gains 225 bonus attack range and 30/60/90 AD for 12 seconds, after using this ability.

Thoughts?
