It seems some people absolutely want their Dunmer to look like the natives from Morrowind. But let me ask you, if your character grew up on a farm in Skyrim... why would his skin look like an ashlander? Sure, some want to roleplay that their characters came from Morrowind and that's fine, then they can have ashlander-skin. Otherwise it does not make any sense to me :shrug:
A nice detail would be variation, a lot of the dunmer have probably migrated. So make textures for both "ash skin" and normal skin. Let the player choose. And even if a lot of dunmers shouldn't have the morrowind-voice since they're not born there, at least
don't give them the dorky almost enthusiastic voice they had in oblivion, it dosen't (imo) fit well with the race in general.
