That can only occur in a 1v1 situation, really. In teamfights, he will be able to utilize it against multiple targets while slowing down one person, dependant on the player's choice.

I have thought about making the damage dealt via the projectiles scale off of a percentage of the damage dealt plus a percentage of Zero's total attack damage. I'll probably change it today, nevertheless.

Yeah, the passive seems to be slightly broken. Then again, double crit chance and a shield seems totally balanced, right? I've gone ahead and reduced the base amount of bonus AD granted and reduced the amount of stacks Zero can gain through Unrivaled.
