I've been hanging out in Stranglethorn because I'm broke, and this place is leather heaven.
Sadly, even though I can make cool things like Toughened Leather Gloves, someone on Bladefist keeps putting stacks of them on the Auction House and selling them for nothing. So the best I can do is give them away to friends.
Anyway, while in Stranglethorn I completed the tiger hunter quest which included battling Sin'Dall. He's not real easy at 33 and he took me down twice before I was successful.
Of course with my luck he dropped nothing but the quest item. Oh well.
