Just a heads up.
In Pearlfin Village, just at the start of the level 85 zone The Jade Forest, so many people pass through this quest Road Rations - Quest - World of Warcraft and leave the corpses un-skinned.
I managed to get a couple of stacks of Exotic Leather and Sha Leather just while doing the quest and skinning what was left laying around. Almost capped Skinning already.
You could probably farm this for some decent g/ph.
I'd use this before the traffic slows down, my server is still jam packed most hours.
Sorry if it's a repost, did a quick search with keywords and didn't see anything. I'm pretty baked.
