So I was flying around SW, and found something useless but mildly interesting. There is a point outside the Mage Quarter that has Westfall, Stormwind, and Elwynn Forest very close to each other. Flying from point A to B (Westfall to Stormwind) takes about a second, while flying from point A to C (Westfall to Elwynn) takes about 5 seconds. This could be fun if you want to talk in all chat channels at all times... or something.
Here's a simple image showing where on the map it is if you want to fly there yourself.
Anyways, how to get there:
1) Head out of the Mage Tower, and turn around so you're facing the portal:
2) Fly up and to the right. You want to be aiming towards the trees, and able to fly over the wall:
3) Fly straight. You should see some orange-ish looking hills up ahead. This is where Westfall starts.
4) Head past those hills a bit. Now, you're at the correct place. Simply fly in a straight line to either zone into Westfall, Stormwind, or Elwynn:
If you want to go into Westfall, align yourself with this hill:
Stormwind, this hill:
Elwynn you'll have to fly a bit but align yourself with this:
Ta-da! You can now go into any of the 3 zones chats just by flying a bit. I personally like to go back and forth between SW and Elwynn, talking to CRZ members in Elwynn and trade chat in SW. As always, if it's a repost, delete, or feel free to move if not in the right section. Didn't think this counted really as exploration.
