This was not my first exploit ever but it was my first that I was really proud of and that I didnt have seen on video before. It was the area next to deathknell, next to UD starting place. I remember it because I had to wallclimb alot to get to a place where I then had to use those blue rocket boots that you equipp to jump over a gap and land it, wich was rally hard and took some tries :P I didnt use the same way as the guy in this https://www.youtube.com/watch?v=CaMYkd7sunM I came in from the south some how, I think I got pictures left of it on an old computer.
Another one I remember was this "room" in Ironforge where me and my friends could stand and kill Alliance. We ran in and died just underneath it and then jumped up to it as ghost. When we was new to it, it was pretty hard to land the jumps but after a couple of days it went smooth. I cant find any video about it so ill go take a screenshot of it and post, brb
