NO LONGER WORKING. Blizzard just hotfixed his loot table.
Were being watched <.< >.>
In the 3.0 patch Blizzard included a new zone in Un'goro that has level 77-78 Npc's.
You can farm these for high 70's items with a hunter, or a melee with a healer. (Casters get resisted constantly and when you hit its reduced)
EDIT: Apparently Blizzard removed the drops from most of them, but the guy in the back, the humanoid, still drops everything (cloth, greens, blues?, etc.)
Ive been pulling him out with my pet then kiting him (so I don't have to kill the others) and once you start kiting him the others will break off if you don't hit them cause they are not linked.
How to reach them:
Edit: Now with video! Other videos posted later as well from other users.

You Must go to marshal's refuge and find this place (Right behind the Flight master)
From here you must use wallwalking (Works in 3.0) NOT WALL JUMPING.
Once you get up, continue climbing a bit and you can now see the npc's.

Enjoy! These guys can be tough for some classes, so you might have to bring a healer.
EDIT: SCREENSHOT OF LOOT.
Reports indicate that drops got removed from the normal guys, but the dude in the back still drops stuff. I used eyes of the beast to pull him out then kited him with cheetah and the adds broke off.
