PAssive: It works based on the raw health gap between himself and his target. Whether he has more or less does not affect the damage.

Temptation: I've had trouble balancing this. But you should note that early game, the damage is pretty low, and it only scales off of (what is now) 30% of his AP, which isn't much. It can be a skillshot, sure, but the early game isn't as high as you're picturing it. LATE GAME IT IS GODLIKE, but any champion is pretty strong late game. So think of it from a leveling perspective.
