How Aatrox could be reworked

I think Aatrox could be changed into teamfight oriented fighter who would target front line instead of backline

Passive: Aatrox basic attacks deal 50% of his total AD + (1% for every 30 total AD) of your targets maximum health (if you have 300 total AD, you deal 150 + 10% of your targets maximum health as physical damage). Aatrox basic attacks drains health from him (50% of damage dealt), unless under 10% of his max health. Every third attack against the same target heals him for 110% damage dealt. If Aatrox kills a unit he heals for 5% of his missing health.

Q: Would stay the same

W: Doesn't have cooldown but can only be activated after killing 30 minnions or getting kill or assist.

When activated Aatrox becomes invulnerable and heals for 10/15/20/25/30% of his max health (similar to his passive)

If Aatrox would die, this ability is automaticaly activated, unless he can't cast spells (he is stunned/silenced/other reason)

E: It still passes through minnions and monsters but doesn't pass through champions

Champions hit are marked

Aatrox gets bonus attack speed vs marked champions

R: He gets increased attack range, bonus attack speed, 50% bonus armour penetration and heals himself and nearby allies for 20% of damage dealt.
