It's not a matter of point of view. Vampires are over-used, with a variety of meanings in all form of entertainment to the point where they don't really have a meaning anymore. I don't recall seeing Snow Elves before, especially not like how Bethesda portrays them.
Yet there are people that want to see vampire-related content. Same as for the Snow Elves. Frankly, Bethesda already have too many cliches. Generic fantasy world, dragons, swords and magic, alchemy, elves. Elves have been done to death, so are dragons. RPGs started off with Dungeons & Dragons. I don't mind the Snow Elves, as long as it is not the main part of the story.
Face it. Vampires are used a million times more than mutated, sightless, monstrous elves.
So are prophezied heroes destined to save the world from an impending doom. Your point?
I guess there is no argument for this one.
