Like I said I've been liking the newBlizz going on(Sue me >.>).
Its kinda what I said, doing Torghast in a tower of the damned is a nice theme but..... the enjoyment gets worn out over time. A new environment as you said would IMO made it more pallatable. How they can do that, I don't know exactly but it would be better.What Torghast needed was far greater variety in environments and mobs. We needed the Island Expeditions content with the Torghast gameplay.
