okay, so I checked Rengar's page, and I realized that the healing on his Q got much more different. Now it heals him more when he has less total health, scaling based on Rengar's level, rather than the skill's ranks.

So yeah, I was wrong about the scalings on E. Rengar's levels equals the healing. I guess that's good if he's getting dominating his lane.
