Oh, I thought you just said that out of the no where, or you were responding to someone even though no one else said anything, my bad. Werevultures don't seem that interesting, plus unless Bethesda goes back to none walled cities like in Morrowind they will not let us fly.
Werevultures would be cool, but like you said they probably couldn't fly, they'd most likely hover like vampire lords. And if bethesda adds any werecreature, I'd prefer it be werebears.
