I prefer to have a choice, than aving none. 2 voices? Ok. 20 voices? Even better.
You want none? Turn it off. You have your way, i have mine.
Everyone is happy.
Except Bethesda, who ends up having to record many, many times more voice dialogue since the dialogue is driven almost entirely by the player character and every line spoken by that character (which would include probably somewhere around a third of the lines spoken in the overall game, again because of the player's involvement in the dialogue) would have to be recorded for every gender of every race.
It's not even remotely feasible for them to do this, and most of their fanbase doesn't seem to want it at all. Don't expect this series to ever have a voiced main character.
