Right - so this is my first attempt at contributing. First I'd like to say sorry if it's a repost - I really couldn't be bothered looking through all of the 101 pages if exploits. Second of all I'd like to thank for a good community who has spiced up my WoW when I've been bored! +Rep
So, this "exploit" if you can call it - involves a bit of basic wall jumping and some patience.
Most of you will know that defending Captain Galvangar in Alterac Valley can be vital for winning in AV. And I'm sure all of you will know not many do actually defend him. So here's a little tip how you can solely - with decent gear - wipe a whole ally raid trying to kill Galvangar.
(also as an extra tip I just found out last week, to get to Galvangar as fast as possible you can as a Warlock lifetap and hellfire yourself to death, and if you can't walk through the gate as a ghost (right corner) you can wait to ressurect at the spirit healer until the battleground starts. It usually takes about 9 seconds after the BG has started to get ressed from the spirit healer - BUT this will spawn you at IB graveyard, ahead of everyone else) Screenie:
1. Head to Galvangar as soon as possible. In his fortress you will see "balconies" on the walls. This is where you'll want to get to.
2. How to get there: (bear with me on this one - i was trying to take screenies and avoid allies at the same time, i fell down a few times so the screenies are not fully synced, i.e. they're not all from the same attempt. But they give you a fair idea how to get up though.

From up here you can wipe whole ally raids if they don't see you, seed of corruption is ace from up there. Other DoT's are also very useful as they don't leave any trace which minimizes the chances of you being spotted. Unable to be attacked by melee-only classes you will definitely end up on top of the scoreboards!
THIS ALSO WORKS IN DREK'S FORTRESS!! And in Orgrimmar battleground room - why you would wanna do it there I don't know though :P
