A pretty nice spot i found at Tol Barad Peninsula. It's not something really exceptional but its useful especially as a caster against melees. Reminded me a bit the VoA ganking spot. You will see many alliance or horde there, doing their dailies. If you dont like it, just skip it.
Here is the spot at TBP map.
So you are at the bridge. Start climbing the chains you see at the pictures. It's a lot easier with mount.
After you climb it, continue walking closely to that "dome". (Removing mount is recommended).
After you reach that spot, start backpedaling to the arrow destination.
Congratulations!
