I just don't like how after Dawnguard came out every single character build out there used Vampire Lord (Even I'm guilty of this). But I love the storyline, I love the characters added, I personally think the Vampires look badass (them eyes) and The new armor looks sexy as hell. But it is your choice.
Yes I agree High Priest - it seems pointless having those features in. I know that you there is the sun penalty, but I never really feel motivated to feed without the hated and feared feature. It creates a sense of fear, when you know that if you're caught, the whole town will be after you.
