I love the fact that ALL vampires are getting a touch up with this dlc. It will hopefully improve an aspect of Skyrim that was lacking before, increasing the quality of the entire game as a whole - not just adding a new questline.
I really think they shouldn't touch up all the vampires and make them all look different. It interferes with certain quests and characters that depend on vampires blending in. I think
some of the vampires should stay as is, others should get overhauled, and others get the whole Vampire Lord thing.
This would make the different types of vampires feel like different bloodlines, rather than one large group that don't associate with one another.
