I just hope his introduction in the full game isn't quite so jarring. I honestly thought he was a EA revive bot that was going to be removed because of how awkwardly he was introduced.
Hes not that bad if you wake him up from his crypt first.
While I like the scene in the crypt, I hope they change a bit what he does after it and how we interact with him. You meet this apparently very powerful undead guy, he helps himself to your camp, offers to help you but refuses to elaborate why, and just stays there doing nothing in case you need his services. Same goes for the oathbreaker knight, I think it'd be more appropriate if instead they gave you an item you could use to summon them whenever you require their services. Having these 2 powerful beings just idling away the hours at your camp sounds a bit ridiculous when you think about it.
