Make Aatrox an "Olaf" type champ.

Aatrox is not an **realiable **melee carry, too weak on early game, easily killable and brittle.

A short resume of a possible rework:

Passive : Blood well, 15 % of Aatrox total HP + 20 per level, each kill grants 30 extra pool points, assists would give 10 points. Upon taking fatal damage will consume the actual amount of pool blood and convert it to HP.

Q - Remains the same.

W -
Blood thirst: Each third strike will heal 20/30/40/50/60 + 2%/4%/6%/8%/9% of his actual hp. Blood price: Each third strike will deal damage based on his actual HP + a flat portion. 5%/9%/11%/13%/16% + 30/45/65/85/95. Costing the amount of HP used to deal the damage.

E - Blades of Torment: Passive: Your basic attacks will steal the movement speed of your enemy. 3%/5%/7%/9%/10%, lasts 1 second. Active: Unleashes a wave that steals armour and magic resist to all enemy champions it reaches. Amount of Armour and Magic resist stole: 8/12/16/20/25.

R - Massacre: Taunts all champions nearby Aatrox (same area of Dark Flight or less for balance purposes) and grants him extra attack speed for each taunted enemy champion. Taunt Duration: 0.5 Attack speed bonus: 25%/30%/40%.

This would make him a tankier champion that relies on his HP to deal decent damage and engaging in fights, Spirit Visage, Randuins Omen, Blade of the Ruined King, Hydra,Mercury treads and some Damage/tankyness item would make him a very good type of carry/tank.
