Haven't tried an argonian yet but i'm told they suffer the same problem, they still have fangs but they look exactly like they did before the DLC. No updates or glowing eyes.
The glowing eyes are welcome, but I don't think it would be a hot idea for Bethesda to get rid of the fangs for the beast races if they still have them. It's just too late after post release to get that drastic about certain visual changes, but I wouldn't mind if they changed it so the Khajiit vampires' fur don't change so drastically, however. That right there is a very big complaint, as there really is no reason why Khajiit fur should change color like that when becoming a vampire. And if it's a possibility, I wouldn't mind seeing some graphical improvements to the fangs, but straight out removing them would likely prove too controversial, since yeah, there's some people who don't like them, but I think a lot of people do like them, hence why I like the idea of vampire appearance being determined by blood hunger. Though I think people generally prefer vampires to have fangs/special fangs, considering all the threads of people just ranting about how vampires don't have fangs anymore (which I still don't know is really true, since I don't know if Harkon really belongs to one of the vanilla vampire races or not, he does have his own unique vampire lord form, after all).
And you know something, if that rumor about vampires not having fangs anymore is untrue, then I'm going to be pretty sore once again, since that rumor has gotten me to start thinking about a whole mod project about adding them back in if that's really true. At least on the bright side, the project could instead be repurposed to add fangs to female vampires at the very least if the "no moar fangs

" rumor pans out to be false.
Also

at how the "type" emoticon turned into the actual image.
Finally, FYI, I am one of the people that actually does kinda like the way vampire fangs look in vanilla for the beast races. Just wished that they weren't so glitchy sometimes, like how the roots of the teeth on Argonians can clip through depending on your character's face. At least it's not TOO noticeable, though, at least in the case of Argonians, anyway. I would be like this

if they ever decided to get rid of the fangs entirely.
