I think they got rid of the fangs because too many people complained about how awful the fangs looked on the beast races. I personally think it's dumb that they got rid of them after so many complained in the past about how they didn't get to have fangs like the other races. Now nobody gets to have fangs, and it'll likely stay that way despite the fact people have been complaining from the beginning how most female characters don't get to have fangs as a vampire. It is also ridiculous how vampires can't use the face-changing option or crossbows as well. It seems crossbows are to Dawnguard as werewolves are to vanilla Skyrim, where they are strictly restricted to a very specific story they wanted to tell and that for some reason they don't want anyone outside the Dawnguard faction to have and use one.
Where are people hearing u cant use crossbows??!!! I still have my crossbow with me in my inventory
Spoiler
