I found a neat little trick that will allow you to climb up any mountainous type of area. (It cannot be a straight 90 degree wall). It's helpful in some cases, especially for range users in Stormwind.
Steps:
Step1: Die. Simple enough.
Step2. Before you click on "Release Spirit" press Esc and click on 'Logout.'
Step3: Right after you click on 'Logout' click 'Release Spirit.'
Step4: Now that you're in ghost form, you should be able to walk around even though you are logging out. With this you can walk up any angled wall that isn't 90 degrees.
Step5: Once you reach your area, or by the time the 20 seconds is up, click 'Cancel' on the Logout so you do not actually log out. You can if you want, but it's a waste of time to re-log.
Downsides:
--20 second limit.
--The area you want to scale has to be near a spirit healer.
--You must die near that spirit healer so once you do reach your destination you can res. and be up there, where ever it may be.
I found this on my own, if it is a repost I apologize.
Credits go to me for finding and posting, again, unless this is a repost.

Requirements: Two players, Anyone who can incapacitate, stun, or halt movement (of the opposing or same faction), and the one wall climbing.
Steps:
Step1: Have both players near a wall, and have the person who is wall climbing (from here on known as target Alpha) target the other target (from here on known as target Omega), tap Esc button and bring up the list of options (you will need to re-select Omega).
Step2: Right click Omega to bring up the options, and then go down to logout, click it, and quickly click duel. (Mind, this is if it's the same faction)
Step2B: If it is an opposing faction, just click logout.
Step3: After the countdown for the duel to begin, have Omega hit Alpha with the incapacitating, stun, or movement impairing attack/spell right away, and if it is not a stun, have them break it by hitting them with normal attacks.
Step3B: If it is an opposing faction, once you click logout have Omega hit Alpha right away.
Step4: If done correctly, you should be able to now scale the wall.
Step5: Click 'cancel' on logout before it reaches 0. (If you're target was a Rogue, they can Shadowstep back up to you and you may repeat)
-Here is something extra for those Mages with a working blink (that doesn't jump you forward, but actually teleports you)
Mages:
Step1: Click logout.
Step2: Blink.
Step3: Scale a wall. Cancel before 0.
Downsides:
-20 second limit, still.
-Shadowstep may bug the character, and you won't be able to keep doing it.
All credits go to me for both finding and posting.
Thank you for reading, and I hope you enjoy ^^
