Yorick rework

I've been watching some Yorick gameplay and he looks really cool. The only problem that I have with the rework is the gouls. The A.I seems that they do whatever they want and doesn't target a champion like Yoricks gouls right now. They seem just like minions. I know that Yoricks e makes them target certain people but that is a area effect and might still not target the champion. So i was thinking if you hit the e on a champion and minions at the same time then the gouls will target the champions first and if there are no champions hit by the e then the gouls will attack the minions. And if you were to change it this way the e can still be useful for letting the gouls jump on the targets faster. Also if the gouls A.I could target the champions with out the e that would be great. But I see the problem with my change because this can make yorick overpowered so you guys can make it whitch he would maybe have this change but make it balance. Thank you for reading this and have a nice day.
