So, yesterday I thought I'd try an alternate way to get on top of orgrimmar (the mountains in the inner part of orgrimmar) and I found a way that was much much quicker. As far as I know, you're required to have an epic ground mount aswell as slow fall. I frapsed the jump on a live server TODAY (February 8th, 200 and it will show the whole process of getting there. Please leave a comment!
