For the monk I enjoyed the idea of using a cog as the strawhat equivalent to the pandaren style.
A 'stealth suit' with a little mechagnome nod. For the rogue I wanted to create something whimsical at the time. After finishing all core races, I took a look at it again and decided for a new jetpack themed outfit. From the very beginning, I wasn't too happy with the hunter design. I had a Wielding Mask inspired helm on my mind for years. The Warrior was one of the first sets created in this project.
