Agreed. All duties from now on should be fully voice-acted as well as more and more cut scenes, especially those related to normal and alliance raids, should be voiced as well.

There's no excuse whatsoever to not make this a reality, and especially not an economic one.

Dungeons and other duties are filled with great text and all of it should be voiced for a greater experience. I recall the defense systems of Alzadaal's Legacy, for instance, going haywire, yet it just doesn't feel the same without a voice attached to it.
