Copypasted from my previous comment on [quest=32892]
Mishi will not offer you a quest until you have certain prerequisites. However, fear not! This strategy will allow you to get up to Chromie without flying in Pandaland or doing the annoying quest/rep grinds to talk to Mishi.
1: Delete your hearthstone. (This step not necessary if your hearth is on cooldown already)
2: Go to the Mogu'shan Palace instance portal. (Not inside of it)
3: Use the auto-unstuck feature (Customer Support>Character Stuck!>Teleport to Graveyard. If you still have your hearthstone and it's off cooldown, the teleport to graveyard will simply use your hearthstone. This is why you delete your hearthstone.)
4: Release your spirit. You will now be mounted on a spectral gryphon. See where I'm going with this?
5: You can't go straight up to Lorewalker Cho, the distance between the balcony and your corpse is too great. However, you are able to resurrect on that little alcove above Mogu'shan. Resurrect here (the topmost ledge is probably too far to accept your corpse, so just resurrect on one of the lower shelves)
6: Use the auto-unstuck feature again, preferably on the topmost shelf, but I'm not sure if that part is necessary.
7: You're back on the spectral gryphon. Fly to balcony where Cho is, and accept your rez.
8: Congratulations! You can now turn in this obnoxious quest. Don't forget to set your hearth back to your faction's shrine when you're done.
Just as a note, using the auto-unstuck feature will NOT result in a repair bill.
