My Aatrox re-rework?

First: Sorry if my english is bad, i don't know it too well I wanted to hear what you guys think about the Aatrox re-rework i made (it's probably broken xD) Passive: The passive from the e, plus everytime you hit a q on the crit zone you apply double the healing form it Q: You can move while using it, but you're slowed. W: More cd, but can go through minions and it slows more E: The current Aatrox passive, but it deals enemy's actual dmg instead of maximum health. R: It also upgrades the other abilities (You can cast q without the slow, your W will drag all the enemy's who where in the zone when you used it, and your e will deal max health dmg and mutilation will last longer) It's probably op, but i wanted to know what you guys think about it or another changes to him.[slayer-jinx-catface]
