Plus I never said they don't go out to feed or go into a town to feed I said they don't CARE for mortal affairs/politics like the cyrodil vampires. I still think thats keeping to themselves if they only go out to feed.
Except:
Spoiler They have you go out and turn villagers into vampires as part of a Radiant quest
Also
Spoiler After installing Dawnguard, you find that the court wizard of Solitude is infact a Volikhar Vampire, yet she is described by the court as blending in and no one knows of her true identity. She is disguising herself for power amongst the elite.
That certainly seems like they care about more than just inner politics, they want to blend in with society just as much as any other Cyrodilic vampire. Its just another example of the lore being contradicted.
Complaining how things are "unoriginal" is quite redundant because frankly, nothing is original. There are many references in Morrowind to ancient Japanese mythology and history for example...
There is a fine line between originality and copy pasta from other Media. Your own example pretty much contradicts your reasoning.
Not only did Morrowind borrow from Japanese mythology, it burrowed from Islamic, Judaic, early Christianity, Roman history, and more. Only it didn't copy paste these ideals, it blended them by creating a unique and engaging story that was influenced by these events.
The chimer following a prophet to new lands. The holy trinity. The persecution of religious practices. The abandonment of an older religious practice for a newer, following a new prophet. Only these aren't directly copy pasted, they have a unique twist on these past events, and are blended with others to create a unique story.
Whereas, volikhar are nearly ripped straight from underworld, and abandon much of what creative and original aspects the vampires had.
There is a major difference there. One is more creative than another.
