Hey ya, here we go!
**You need a way to slowfall and a way to increase speed**
1. First off, you need to go to the hunter's trainer area in Orgrimmar. (Located in the Valley of Honor.)
2. Go into the stone "hut" area, and look for the place that looks like my first SS. (it is the path leading out of the trainers area)
3. Jump onto the wall. You will need a sort of speed increase.. I used Ghost Wolf, but mounts and potions work as well.
4. After getting onto the wall, walk around and go up onto the wooden "spike"
5. Now, you will use noggenfogger/slow fall/etc. to jump over to the building.
6. Now, walk around the left side of the building.
7. Continue along the other side, until you reach the wooden wall.
8. Here you will need a type of slow fall.. and if you used noggenfogger, it should still be active.
9. Jump over the wall, and you will fall down under Orgrimmar. (see SS for exactly where to jump)
10. Congrats! You are now under Org.
Anyway.. hope this tut wasn't too terrible.. and most of you can follow it at least.
Thanks for reading!
