Yeah so.... about a 2 weeks ago I figured out that the Dawnguard Add-On was about a new vampire lord play-style along with it's own perk system and the werewolves new perk system, it's very Underworld inspired I can tell. With my time with Skyrim, my one & only player character that I use (who has a lot of experience, lvl. 50+) was originally a vampire, then when I was in the middle of the Companions quest-line I was forced to become a werewolf. Now with this in mind I think I
might have a problem becoming a vampire lord, because I think you might have to be a normal vampire in order to become a vampire lord?
