So I was running around Ruins trying to find out how i jumped out again i did it and i found a instance portal to SFK , i wall climbed the side of the castle and got into uninstanced SFK inside Ruins of Lordaeron arena.
If people request it I can post a guide on how to wall climb out of the arena.
I didn't manage to get many screenys of the other areas of it because the match only lasted like 4minutes :S
Enjoy!
