DLC Speculation: Masters of Desth

My personal hope/expectations for a Lord Pack DLC covering the undead factions.

It would come with the lore of undeath, updates to the Vampire Counts and Tomb kings, and a unique faction for Nagash, the Undead Legions. The Undead Legions campaign mechanics would be unique and focus on growing Nagash's personal power, as well as mechanics to grant him access units and lords from the other undead factions after conquering them.

Would love to hear your thoughts on how you want the undead covered in WH3
