Scale Yorick's Q heal with something...
This is based off another post. Yorick's Q heal is pretty weak right now; doesn't allow him to get the sustain he needs. So I think it should scale with either (all still x2 when below 50% HP): Level: (15 per level) AD: (+30/35/40/45/50% bonus AD) Health: (+25% bonus HP / 5-6% missing HP) Something.
