Yorick feels extremely clunky
He hasnt been touched in months, yet even since the rework he feels clunky.
His autoattacks have the worst windup, and saying that he has an auto reset or builds Triforce doesnt make up for that fact. He isnt going to only use Q to CS in lane.
His minions, like most minion AI (except new Malz) aren't exactly the best help. They dont target focus unless yorick uses E. And his ult has some of the worst summon AI in the game. It doesnt take inhibs, or rather, doesnt seem to know how to, but rather walks forwards and backwards while the wave tries to do damage. Even if Yorick is there, it still takes MotM about 5 seconds to target the inhib.
Overall, Yorick feels exceedingly clunky for a champion that was reworked in 2016, he still feels like his code is from 2011.
