I like how the new Yorick feel but many things are boring :
- ghouls have extremly poor HP and average damage
- it take a long time to activates ghouls early on
- the ultimate is powerfull but non-controllable
- the E is too hard to land, i think that's the hardest skillshot to use in the game
- the Q spell healing is useless outside of laning phase. Who care about 100 hp when you have 4,5k ?
- Yorick is very dependant from ghouls and can't do any damage without them or ultimate
- He is good in lane ... and that's all : useless in TF, useless without ghouls and Maiden, useless later 1vs1 too
- Yorick is countered by most toplaners (dashs, AoE cleave, hydra, sunfire ...)
As for Kled, most people will say that Yorick is OP, but he will be pretty weak.
