Had one game with William Yorick and baseball bat. I don't quite see why it is a good fit at all. An auto fail leave the player encountered yet unequipped. Two hand slots means there's no backup weapon. Yorick can only retrieve assets after a defeat. Any two health enemy, at level difficult, could be hard to defeat at difficult level.
I Immediately swapped to .45 Thompson, and eventually went for old hunting riffle, by which time the risk can be managed with eucatastrophe and will to survive. and most importantly old hunting riffle, while jammed, is a valid candidate of act of desperation, which can loop with Yorick's elder sign ability and resourceful.
