A Yorick rework is the perfect time to create a very unique and complex champion.
Currently, Yorick's gimmick is to summon ghouls that harass and annoy the enemy laner, each having it's own powers, this whole concept is already pretty different but it could be done better. A rework is also a perfect time to use the Pet mechanic.
This mechanic is barely used. Normally the things players spawn in are AI controlled (Heimer's turrets, Yorick's ghouls, Elise's spiderlings). Mordekaiser and Yorick are the only ones I can think of that can manually control something. Both of them expire however. What if Yorick was able to summon a Ghoul and keep it until it dies? This to me is interesting because someone ACTUALLY will focus on controlling two characters constantly for max effectiveness. Nobody does that yet. There are many ways this can be used, making him a flexible and diverse character. I have a rework idea for him, I hope riot takes a look at this(even though they probably wont) because I think this idea is very cool. I am also interested in what you guys think.
NOTE: I will not be posting damage ratios and such in this as I don't want comments to be about OP damage and such, more about the overall concept.
Passive/Gravedigger: Dead Minions/Monsters/Champions leave a corpse and can be buried for varying bonuses. The corpse will expire after a certain amount of time(maybe 10 seconds?)
-Minions/Monsters restore a tiny amount of mana. Doing this requires Yorick to channel for maybe 1-2 seconds.
-Champions can be buried to take a small portion of their re-spawn time off. This could take maybe 5 seconds.
Q/Graveyard Smash: Yorick causes a corpse to explode and deal magic damage in the surrounding area(Scales off AP). If this is used on a champion/Ghoul, the damage is increased and the AOE is slightly increased. This ability will destroy the corpse, making him unable to bury it.
W/Tainted Aura: Toggle: The souls of the dead that have been put to rest surround Yorick. Ghouls/Zombies near Yorick will heal, enemies that die near Yorick have a small chance to reanimate as a Zombie. The heath and damage of the Zombie scale with Yorick's bonus damage and health. Enemy champion corpses will automatically turn into a Zombie when in range. The aura also slows enemies by a small flat amount. Yorick can use Q on a Zombie.
-The Zombie does not reveal shroud and will attack any enemy units nearby. The Zombie does not disappear over time but there is a limit to how many can be on the field at once. The Zombie is very slow moving and doesn't hit hard. If there is no enemies in range for it to attack, it will slowly wander around, maybe dying to a jungle monster or tower if it is alive for long enough. Yorick can also inanimate these Zombies. They are pretty easy to kill so they do not heavily zone enemy champions.
E/Raise Unrest: Yorick causes undead hands to rise up under a target and grasp at it, rooting it in place. This ability is point and click but it has a delay, so it can be dodged. (Think of Lucian's Q).
R/Summon Ghoul/Spells of the Dead: This is a toggle ability(Like Jayce, Elise & Nidalee). That gets unlocked at level 6. When Yorick goes into "Summon Ghoul" mode, his Q, W and E turn into summoning spells. Each summon requires him to channel for 3 or 5 seconds. Ghouls cannot get too far from Yorick however. Summoning a ghoul takes a large amount of mana(Enough so you cant just sit back and spam the Ghouls all day)
Q/Summon Angel: Yorick summons a white ghost in robes and a hood. This Ghoul cannot attack and it untargetable. While it is active, Yorick can move through units and has a small movement speed boost. Yorick can bind this Ghoul to an ally, causing it to follow the ally around. This increases the range it can go away from Yorick by a little bit. If it is too far, it will unbind and return to Yorick. When the bound champion dies, the Ghoul flies into the corpse, bringing the champion back to life for a short period of time(like his original ult). If Yorick does while the Ghoul is active, it will fly into the champion that did the killing blow and deal one hit of magic damage(Scales off AP).
W/Summon Reaver: Yorick summons a bleeding Ghoul(Reaver). The damage and health of this Ghoul scales off of Yorick's Bonus health and damage. Reaver's attacks will heal Yorick and when it is active, it will increase Yorick's attack damage. This Ghoul is naturally faster than Yorick.
E/Summon Titan: Yorick summons a large Ghoul(Titan). This Ghoul is tanky and moves at an even speed with Yorick. Yorick gains bonus magic resist and armor while it is active. The damage and health scales off of bonus AD and health. This Ghoul has a slower attack speed. The Bonus armor and magic resist scale off of Yorick's bonus magic resist(This does not stack off itself).
If you have read this far, I greatly appreciate your time spent and look forward to your thoughts. I think he has a fair amount of strengths and weaknesses. I am also pretty sure he can be played effectively as AP/AD/Tank or even a mix of them.
Thank you for reading this.
