My rogue for your viewing pleasure <3 -Beavertreat
This post is done with a little bit of discretion. As far as language goes, certain words are best left unspoken. Admittedly, Mog's Addiction has some (read: mostly) skimpy sets and innuendo doth floweth free like milk and honey from fertile lands, but I try to keep it clean(ish) for the younger viewers. :p
Now, onto his fantastic set!
The shoulders, I believe, are the focus of this set. They have the model of the rogue tier found in Dragon Soul, however you will be VERY hard pressed to acquire that particular color these days. The pair he is wearing was found in Raid Finder mode. So, unless you can get a level 85 character and 24 other level 85 characters to queue for it, you might be out of luck for that particular color.
The tier shoulder lookalike, Underdweller's Spaulders, are amazing in their standard and heroic raid colors. You aren't completely out of luck. Beavertreat has a little treasure her rogue can wear whenever he feels like it. The impeccable choices of this set make it worthy of adulation. A little leather never hurt anyone, unless you are on the wrong end of the daggers. :p
