Aatrox Rework redistributes his power
As I said in another post, Aatrox is vulnerable and easily counterable because his escape, his engage and his CC is all tied up in ONE ability. Unlike say, Jax.
Dark Flight:Aatrox can hover the cursor over the ground to jump to target location. Additionally Aatrox can target an enemy champion and dive to target enemy champion, slowing them and doing damage to them and nearby enemies upon landing. If Aatrox targets an enemy in the air, Aatrox plunges his sword down into them, knocking them down to the ground and doing bonus physical damage. Blood Thirst/Blood Hunt: Aatrox passively gains health every 3rd attack. ACTIVE: For 6 seconds Aatrox gains movement speed and and in addition to healing every 3rd hit, deals bonus magic damage every hit. Blades of Torment: Aatrox does damage in 2 converging lines that erupt upwards. Enemies hit between both lines are knocked up for 1 seconds and suffer reduced magic resist. Enemies hit by one line are slowed. Massacre: Same, but AOE damages monsters and minions.
There. Every rework idea should be that short. The details can be worked out, just give us the basic concept so it doesn't take 10 minutes to read.
