What the [censored]? No seriously, what the [censored]? I noticed Harkon has no fangs!
Vampires do no burn in sunlight.
Vampire no longer have fangs.
What is next? Vampires glitter in sunlight?
I noticed that Harkon didn't fangs in the trailer.
Vampires can use crossbows just like any other weapon, they just don't find a lot of them. Crossbows are meant to be rare for everyone but the Dawnguard.
Well now I've heard it both ways. I've heard from one person that vampirism bars you from using crossbows, and now you're saying that they can use crossbows. Someone better go and double check that you can use a crossbow as a vampire and take a screenshot of it if possible.
Looks like it's up to mods yet again to fix the problems of everything.
Yeah, I'm currently like this

right now trying to figure out how the fangs are implemented right now. I'm getting the impression that a mod that adds fangs to vampires would have to be done as an equipable item using one of the unused slots, since I think that FaceGen stuff is done using an application we don't have access to. Stupid lemons wreaking havoc on an otherwise awesome-looking DLC.

Why take away one of the unique things about Argonian vamps that other vamps didn't have? What's next, are they going to take away the pale/grey skin of a aronian vamp? Dawnguard is supposed to make vamps cooler not lamer. I really hope they don't take away the fangs of the Khajiit vamp (the ones that make you look like a sabercat)
Yeah, I have no idea what they were thinking myself. Maybe they'll add them back in if there's enough complaints about it? Then again, there's still no spears, wild lycanthropes, werebears, or general improvements to magic yet, either, and those are ALL big demands. Of course we don't know what will be in Hearthfire yet, though.
