Aatrox has very little utility and perks from his abilities---here is a fix @meddler
Blades of Torment, add in "enemy champions hit with the blades are tormented multiplying the remaining cool down seconds on any abilities on cool down by 1.1, 1.2 1.3, 14, 1.5.
So for example, if you hit a champion with one ability on cool down and the blades hit when its at 10 seconds, it will be moved to 11 seconds, and at max level it would move it to 15 seconds.
This is not only unique but helps give Aatrox something to slow down enemies with who are ability based. Other champions have the abilities to slow attack speed, and items that also slow attack speed, which shuts Aatrox down...why can't Aatrox have something to fight back with?
Blood Price, add in does bonus magic damage to on hit to enemy hit with basic attack after being knocked up with dark flight.
Massacre, add in grants allied champions bonus movement speed and attack speed while moving towards or fighting near Aatrox.
There, what do you think?
