FACT: In Daggerfall all nine clans clould blend into society if you didn't feed on blood you were penalized with an inability to rest or wait. Morrowind broke lore by having vampires be outcasts who couldn't walk among normal humans.
You again?
No, Morrowind did not break lore at all. They added new vampires. In Skyrim, we already had vampires they way that they are, now this overhaul will completely change the vampires we have. I know, it' Bethesda's game and they can do what they want with it. But it seems we have no penalties now.
