Yeah, I think 1 is my favourite, though I think the way vampires are portrayed in Skyrim is for the sake of gameplay and balancing, their lore is quite interesting and unique.

I agree.  The greatest challenge in making a game is usually the balance between lore and gameplay.  The actual lore is fascinating but their practical power makes their limited numbers... less than believable.  All they have to do is use their leaching spell to spread the curse and that can be done at a distance.
