After PvPing for about 8 hours...I was just messing around and here is what i found....
(first of all. i dont care if i get rep/whatever. Just thought would share it if any1 didnt know....)
READ ALL BEFORE YOU ATTEMPT:
You need:
Epic Mount (Speed Helps get Air)
Patience (takes a few minutes to get...)
HEARTHSTONE (incase the going gets rough...)
First, jump like in image below.
Then Postion urself (give urself some space like in pic)
Then run and jump to the platform
takes a few tries, but you will get it!
Skipped a bit, but after facing wall turn to your right untill u see a pipe that goes up, lets go up the pipe! it takes us a bit up and then left.
From there u can jump down.
WARNING: Takes many many many many tries to get out. I used hearthstone after 10 mins of trying. Then i did it again and got out in a few tries.
If you already use ur heath and cant get out, YOUR STUCK. The game just owned you.
I know this all is pointless but i thought it was... interesting :P
