Zoe change - Lux-like passive

Hi, as a Zoe main, it's really frustrating to see her gutted. A lot of her nerf are reasoned with "she should have less dmg when missing a spell". I totally agree with that. But shouldn't she be rewarded for hitting a spell then?

I have an idea for a change to her passive. Let her QE leave a mark, just like Lux. Increase the passive dmg but change it, so it only affects targets with the mark. (OR buff her Q)
