Yorick's AI

Go to 33 minutes and look at what yorick's ult does? Really riot? you rework this champion to have this great split pushing kit, but give him garbage numbers and an AI that does stuff like this??? I don't get it. On an unrelated note this maokai is just sooooo META right now that it doesn't matter that he got dumpstered all throughout the game he wins because all the tank items give him OP stat's and damage as well. please please please fix this.
