How much is Yorick going to be changed?

Ever since I've seen what happened with Malzahar's voidlings, it excited me to see how AI had improved a good deal. However, AD Malzahar was (and probably still is, honestly) still going to be extremely oppressive for time to come. More to the point, I'm worried that Riot might make Yorick something too different if the idea of AI beating someone to death is overbearing. Will he retain his "Jack-of-all-trades" nature (Sustain, speed, tanky with a side of damage)? Or will he become a sluggish juggernaut that sends in his army from afar? Maybe a sort of sieger who brings an army to surround an enemy from all sides?

Yorick had a fun personality as well; A morbid, yet happy-go-lucky gravedigger who lives on the great Shadow Isles. He comes from a long line of gravediggers, and is undead due to not having an heir to continue the "family business". Are you going to tap into his "tragic figure" personality, and make him more morbid? Perhaps making him only think about burying bodies; A true slave to his line of work(Like Sion's insatiable lust for killing.). Or is he going to be more oriented to optimism, enjoying his labor of putting the dead to rest?

And how will this affect his lore? Does he have a sort of kinship with Karthus, enjoying bringing other people the gift of death? Will he embrace Sion and Urgot, in the feeling of being undead? Or will he find the act of being undead cheating death, and utterly distasteful? What would he see in Kindred, a personification of death itself? The undead digger has an interesting line of work, which will surely lead to some special interactions with other champions.

Is there any tidbits you can tell us, Rioters? Be it from a lore perspective, or a gameplay one, Yorick's rework is a long-awaited one and any details about it are exciting!
