Omg people so...... Braindead. It was this way with MoP to WoD prepatch and omg its the same way now. Npc even tells you this and logic thinking will agree thats ofc the new dalaran and not dalaran of 3 expansion ago. And as you said your self you can not acces it yet. So why even post this if you already got your answere. Wtf you expect to get out of your post? Magicaly have npc ported to your garrison?
OP you fail at logic. How do you survive in the real world?
