Reposted from other thread:
Yorick relies on his ghouls, which is by design, it is his passive. His kit should have more redundancies rather than just more power in healing or damage from him directly. By this I mean the following:
More ways to generate graves outside of just Q, I always suggest graves generation from his W after a 4 second delay (1/1/2/2/3 by rank)
A very small amount of healing (1-5% by rank in Q) from damage done by ghouls (to themselves and Yorick)
Yorick's Q marks targets, nearby Mistwalkers jump to that target doing damage on landing (is an auto attack reset for the walkers)
Mistwalkers changed to have Zyra or Heimer plant health systems (1 hit early, 2 hits mid game, 3 hits late game) to kill
Ultimate no longer summons Mistwalkers with Maiden (Maiden can still generate them by killing things)
Maiden % health damage lowered 2/3/4% (by rank), but 2 second delay between procs removed
These changes create reliability in his kit, allowing him to summon walkers more consistently throughout laning and late game, the impact of which is more than just one hit and gone (amplified by their self healing capabilities), and is prepared for a world where faster auto attacking because of the new Runes system will most impact a large portion of the roster that already hurts Yorick (Marksmen, Duelists).
This is how I would ask them to change Yorick, and is a consolidated list because honestly they could change only the W graves generation and remove walkers on Maiden summon and that really be enough for me. I just want to have consistent power spikes on demand without relying on the long CD ultimate. Then being able to treat Maiden as a split push / steroid tool instead of an emergency walker generation tool would feel much better overall.
and 
, That other thing I would like to see is Yorick's E granting him Slow resist and/or Tenacity when it hits a target so he can properly chase after them.
