I wish I could say the changes to vampirism, but I hate the look of the VL, & I'm worried about what it means for the base vampire.
So, the possibility of more silver weapons.
Considering how atrocious they are at the moment a step in any direction is an improvement, the way I see it. Personally I can't wait for an overhaul of their mechanics. Maybe make their sight power a type of spell instead of a once-a-day power that I'll never use. I hate that crap. Honestly, what kind of vampire can only see in the dark for an hour a day? And then there's Vampiric Drain. I was so pissed when I learned they took Drain from the overall spell roster to appropriate them for vampires in such a pathetic form. TWO POINTS A SECOND? WHAT?
Othwr than that I'm very much interested in how this whole "blocking out the sun" thing turns out. Observing vampires within a social context should be interesting too, as previously I've only seen them as hostiles or within groups of non-vampires. I never got vampirism in Morrowind you see, but I read about it.
The story intrigues me as well. You so rarely see a DLC that you're interested in for story content anymore.
