I don't know if it has been related already, but I found a nice place to heal people who defend Vandar, and also to cyclone enemy tanks to wipe the horde raid.

Actually you can jump on the top of the banners in the boss room :
This is how you do it :
1 : Jump on the weapon rack.
2 : Jump on the metal thiny. (Get your character parralel to the wall, otherwise you will go back down on the base of the wall).
3 : When you reached the metal thingy, do big jumps, and when you're at the top of your jump, move a very bit forward to stabilize yourself a bit upper. It's like walljumping back in TBC. (Stay parallel to the wall, it's easier)
4 : When you're close to the top, look at the opposite wall, and to a last jump to reach the top.
For some reason, It's easier to jump on the banners that are on the sides of the room than on the one who is next to Vandar.
The best is that horde almost never spot you :
Hope you enjoy it, and sorry for my broken english![]()
