This is an alternative way to get on top of Orgrimmar and expands on it so you can get on top of the Battleground Center to gank some kids coming out.
Things you need to have to make this happen:
Rocket Boots Extreme (Lite)
Able to maintain a slow fall for roughly 90 seconds
The first half of this is basically this youtube video (this is not my video, but its what I used to further get on top of the BG room in Org)
[ame=http://www.youtube.com/watch?v=5nlKvisRo-A]YouTube - ROCKET BOOTS: From Winterspring to Orgrimmar[/ame]
Jumping from Winterspring over Azshara to behind Org. Follow that exactly then follow these simple steps.
Run over to this area which looks like a huge crater but is actually underneath Org
Run around the right edge of the crater
Now come to this spot and watch your minimap, the base area near the edge is a roof and you must hit this or you will fall towards the floor of Org and if you are Alliance get wrecked by guards.
Now we jump down trying to hit the base roof (YOU MUST HAVE SOME FORM OF A SLOW FALL OR YOU WILL DIE, though its not a long fall the game still considers it a farther fall and it can kill you from 100%)
You should land here like this
We now want to head north along this edge being aware of the slits and holes in the roof so we don't fall (Also as a note, you may want to zoom your camera in, having your camera zoomed out is buggy and can blind you by empty terrain at times and you may fall off). Hug around this edge until you get here
Slow fall down onto the BG building and it gives you an excellent perch for sniping people as they exit the building.
Sorry if this was ever posted before, just wanted to share how I found to expand on a couple ideas people already had.
Thanks for the +Rep if I receive any.
