The Nord, Breton, Khajiit etc. voice actors were OK as well. I just hope that they separate Bosmer, Altmer and especially Dunmer this time.
That they will have more voice actors this time is promising, and I really hope they have gotten at least 20 different ones (1 male and 1 female for all races).
I think they need the voice actor(s) they had for the Dunmer in Morrowind back, because those coarse voice really gave the Dunmer character. Much better than the Oblivion British aristocrat voice. Otherwise yes I think all of the previous voice actors should return. However I think they need to hire a slew of other voice actors as well to add diversity.
You speak the truth. And I hope that the British aristocrat will still voice the snobbish Altmer, while two other voice actors voice the Bosmer and Dunmer. Dunmer really need to sound as they did in Morrowind.
