Game really seems to punish the Dawnguard players, if you side with the Vampires you only have to worry about from my experience the Dawnguard guys who come into towns only to attack you.
say what?! I am so rolling a vampire after this then!

nothing beats being hunted down like an animal. I miss the Thugs coming for me and the random assassination attempts on my life by Khajiit and turning them into boots/comforters.
OT: is it possible to be a vampire while playing with the Dawnguard?
