Didn't see this anywhere else on the forums, so i thought i give my 2 cents, this is a very good spot i found when i was into hyjal 2 days ago.

After you clean the spot up you will notice there is atleast one ogre that keeps respawning immediately, sometimes 3 times in a row at exactly the same spot and when he changes, its about 20 yards east of him. Where the circle is on the map, its pretty much south of that circle (place where you are at) that the ogres that spawn instantly are. What i did on my druid was i stood in the middle of their spawnspots and killed them one by one and looted after i got around 30 kills to take a break. Also they are casters so they wont move at all.
Made about 6 stacks of cloth in an hour farming them. GL
