I never really had that much of a problem with the original designs. That being said I do think the new ones are quite the improvement. I think they chose to show off the ones that are the most similar to what we have now so we could make an accurate comparison. It should be noted, as one person did earlier and was ignored, that each area is going to be split up into multiple zones that will look different. What we're seeing is likely the zone that most closely mirrors the current Thanalan and Black Shroud.
