sorry for necro its just that I played Dawnguard only recently and after finishing it 3 times in row... Well Serana ...I have nothing much against her from game mechanics point of view as after months of soloing I am actually glad someone always is around, BUT...I do not like her that much from my character's point of view simply cause: A - she is a daughter of coldharbour (since I cannot take part in such ritual ingame and be identified with her and Valerica) B - She took part in willingly...my character sees own dignity as top priority. C - Even if she didn't , still there's only this lesser- half- mixed blood option. Oh yes, my character is extremely jealous sometimes so actually she took pleasure dominating over Harkon:P Just to show them that pure blood or not..you are no match.
