There are some very Necromacerish elements surrounding Thm in xiv's story. In fact one of the initial side quests revolved around a head of a Uldah family enchanting bobbles that would cause the owner to raise up from the grave and seek out others owners. Of course the whole thing goes comically wrong when the Creator of the bobbles is killed.

This is not to say that we would be given access to a "Job" focused in the direction of controlling undead. That's more in the purview of the "Bad guy".
