In English-
I have, for fun, been trying to wallwalk inside some instances, (Molten core, Zul'Farrak) so in the start of Zul'Farrak, try to move left, before the first 3 trolls, then try to stand with the wall on your back and then wallwalk. Im not sure, but it did kind of work for me, but I think it might be a real wallwalk without a Wall Climber, because I havent tried it. But check it out.

So.....It "Kind of worked for me" BUT "I havent tried it"
Skills.
This sounds even dumber in English...
But, well, thanks for trying, but this is rather..
Bleh.
