would it be crazy if we gave grasp the same benefit as dark harvest?

at a certain health threshold, like 3000 maximum health, the proc persists for 5 minutes once its readied.

maybe something similar could work for conqueror to make it better in larger scale teamfights later on. in return its ad/lvl scaling could be tuned down a little. like from 10 to 35 changed to 6 to 20, since it would be easy to immediately proc later on, and already give you the benefit for the first 4 seconds of a fight.
