I hope this post is a troll because to compare yorrick with bruiser fizz and ekko is so laughable.
Fizz was nerfed because no matter how far back your carry was, fizz would be able to hop on them and burn them to death with sunfire and iceborn or trinity with little to no counterplay other than crying.
Ekko was nerfed and will continue to be nerfed because his tankiness, high base damage, high mobility, stickiness and utility.
Yorrick has no mobility, a crappy slow and his wall.
His damage is lack luster as long as you don't get hit by his E when his ghouls are up.
His ult has a MASSIVE cooldown and he's weak as shit without his ult.
Yorrick is pretty bad and is in need of buffs, you just got smashed by a better and/or fed player, deal with it.
