Concerns about new Yorick
I used to play old Yorick a lot. He was fun to play but also a pain to play against since he could just spam ghouls on you all day. Riot fixed this by giving new Yorick a small window where he could trade efficiently. Basically, you get 3-4 graves, raise your Mist Walkers, wall the enemy and go in and smack them around. So far so good.
BUT, this is also where the problem lies. Every single champion with a dash/jump in their kit totally ignores this window and can harass Yorick freely. I know it's too early to take win rates into account but seeing how he has below 40% win rate against every champion with a dash/jump makes me think there is something wrong with his kit.
tl:dr Yorick is being bullied by every champ that has a dash/jump since they can just ignore his W and trade freely.
blitz, is known, hell notorious, for having a very SMALL window of opportunity to engage. His 20 sec Q CD is what defines and breaks him, honestly.
