Well, I just stumbled upon a quest that took me to Moonglade. As the druid I am, 10 seconds later i was in Moonglade (Druids can teleport to Moonglade).
This quest was The Keeper's Favor - Quest - World of Warcraft
After finishing the bit in Moonglade, i got a new quest. The Boon of Remulos - Quest - World of Warcraft
This quest takes you back to the original quest giver in Icecrown. By accepting the quest, you start a small event. The quest giver opens a portal to Icecrown . Now how would this come in handy? Well, the portal is quite close to Dalaran, i mean literally like 10-12 sec flying.
When you arrive in Icecrown you are ment to turn in the quest. I didn't. I abandoned it. Then i teleported back to Moonglade, and re-accepted it, got the same portal back to Icecrown.
Thus making this a way for any druid that has not already done this quest, a possible way of getting from anywhere in the world, to "dalaran", even tho you might have cooldown on your HS, no cooldown. Enjoy
