Yorik needs to be addressed.

So uh... ban him?

As Cliched as it's going to sound, It's Preseason my friend. Everything is going to be insane for at least a patch or two. I have never had the displeasure of facing Yorick in Season 8, but between the Dark Harvest & New Grasp Runes, I can see why he's doing so well. For now, you're only option is using a Ban on him in Champion select if you do not wish to go up against him. Just understand you'll most likely fight something else that will ruin your day. That or learn how to play around him as he does have weaknesses.

As a Yorick Main (or at the very least someone who has alot of experience with him), I'll give you a few pointers.

1.) Yorick would rather pick a fight when he can whip out his Ghouls. Either kill all his existing Ghouls & pick a fight with him or Harass him so he can't generate Grave Markers.

2.) As for his ultimate, make sure it's down before picking a fight with him. Yorick Can Duel & possibly bait you if it's up as he can pump alot of damage in such a short time.

3.)Keep in mind that Yorick is a Split-Push champion, treat him like you would a Nasus (End that game as fast you can before he scales).
