But Bethesda really couldn't think of a more original Vampire Lord form? It's literally the same thing as Marcus and whatever else it resembles. Maybe it could've been a type of wraith or a more beastial form. Not an ugly grey guy with wings.
Well the Vampire Lord form as stated earlier by another poster has become the standard for diabolical Vampire villains in movies.
Dracula in Van Hellsing turned into it...the villain from Underworld turns into it...
Its more or less the modern day version of Nosferatu.
I personally am liking how it looks, gives the Volkihar vampires something special to set them apart from the Cyrodilic Vampires which they were basically clones of in Vanilla skyrim..which broke the known Lore about the Volkihar a lot.
Cyrodil's vampires are the only vampires that feed on sleeping people, the Volkihar like other vampires in the TES universe prefer to sink their fangs into a awake enemy/villager which you'll be able to do in Dawnguard in normal form and VL form...also another thing they are changing is..
Feeding makes you stronger rather than starving yourself which made the Cyrodil vampires stronger.
You get perks in the Vampire Lord skill tree as you feed and Bethesda supposedly added quite a few feeding animations for normal vampire form and VL form..and supposedly some of the VL perks carry over to your normal form..but can't say for sure.
Seems apparent the first perk in the skill tree and Blood healing (feeding in combat fully restores your HP) carry over to your normal form.
