At this point, I think you need to take a brief field trip to Talador to see for yourself how dissimilar the Shattrath dome and Auchindoun look. You'll never mix them up again, I guarantee.
I simultaneously love and hate that I am able to correctly name the zones even though I haven't been in some of them for over 15 years (and I haven't touched the game in 4 years). I even instantly knew the location of the Hinterlands one and I can't even remember the last time I was in the Hinterlands.
