I don't know if anyone had encountered this but theres this bug in the Dawnguard DLC where even if you reach the Stage 4 of your vampire lord perk meaning the blood starved vampire stage where everyone is supposed to attack you on sight.. they don't, Isn't that cool? then theres no need for constantly having to feed on people :)
