absoluteley, pitty it sounded bad in oblivion so that they scraqed it and gave him the elf voice
but aparently he did the realy bad voice acting in oblivion for some males (forgot if this was nords or imperials)
The voice actors name is Jeff Baker. He did most of the male voices in Oblivion, Nords, Imperials, Orcs etc.
He is good voice actor, but too much is too much.
Johnny Depp is great actor, but if he was in a movie that took itself seriously where he plays about half of the characters it would be too much.
The unfulfilling reason behind the voice was that the dark elves of Cyrodil didn't have the voice because they weren't breathing int he ash from Red Mountain all the time. Of course, all the other characters in MW spoke normally... Maybe the Nords will all have the gravel voice in Skyrim because they all have colds.
You are forgetting the fact that Morrowind wasn't the first game to feature Jeff Bakers raspy dunmer voice. Much farther from Red Mountain, in Hammerfell in the game Redguard the dunmer had that "Morrowind voice".
But yes, I hope to see the Dunmer voice from past games return.
