yoricks ghouls really shouldnt be auto attack 1 shots lategame.
it makes sense during the early lane phase to be able to deal with his ability to push and to counterplay him in lane.
but maybe it would be a good idea to have the hit points of his ghouls scale up to multiple auto attacks to take them out, similar to ward hit points. especially since champion attack speed scales up even when you dont buy attack speed items. it just means as the game progresses, people have an easier time to immediately take them out before they can have an impact.
give them 2 hitpoints at lvl 11 and 3 hitpoints at lvl 16. maybe thatll solve some of his scaling issues.

into him and just build
and gain twice the health i normally would in a game and all i have to do is actively face block Yoricks E
Ghouls will then suicide on me and i gain free hitpoints
The longer the game lasts the faster he spawns ghouls the faster i gain hp to the point where you become unkillable
and one of its upgrades, if you have any aoe in your kit even better
hard counters yorick. she can just q reset herself through his ghouls in half a second and then turn on him.
