There are three cloth sets that just grabbed me when I started looting them on the Isle of Thunder. I love them so much that I mogged my PvP gear into one of the sets. Here is Delgada in most of the Faded Spirit-Wrencher set.
Apparently it's a re-run of a set from Zul-Aman, except the shoulders seem to be a re-run from old Zul-Gurub. The shoulders and the belt shown in this picture are vendor gear and not part of the set.
The other sets available are a re-color of the one above called the Forlorn Spirit-Wrencher set and a totally different design called the Exiled Dabbler's set. Historically, the items that pre-date these were never part of a "set", as they dropped at different levels between 60 and 85. I am glad they made these all drop in the same area, so as to make them easier to farm. It is a great look, though one I haven't gathered any of, yet. Seems that others like the look as well as I do, because they are out of my price range on the auction house!
I tried to load up this set on WoW Model Viewer but could not find the set in the files. Then I had this fabulous idea of loading it up with the old set items, only to have the model viewer tell me it doesn't support my version of World of Warcraft. I guess I will have to be a little more on top of updating my add-ons and model viewer when we get new patches!
I have to admit I haven't looked at the other types of armor available on the island yet. Do I care? A little. I have an up and coming hunter and a rogue that may need a new look soon. They're just a little too far off to be looking at gear from the Island of Thunder. So, until then, I leave you abruptly having only covered the cloth gear. Have a great day exploring Azeroth!
