On top of the duplicated terrain which is painfully obvious there is a lack of wow factor when outside the cities. It seems like it would be an easy fix to add landmarks and such to give players the feeling they aren't always in The same spot. You could also try making the camps bigger and different from each other. Little things like this do not go unnoticed. I can run from uldah to the ferry and not see anything of visual interest which is a shame because the graphics are incredible.
