So, this is my warlock I've been trying to find a perfect matching set for. My goal was to avoid using a robe chest piece and a cloak. To me, making him look like this just looks more imposing instead of the traditional robed spellcaster look. I also stuck with using purple themed throughout as most of my characters transmogs are themed to their respective class color. I was especially happy when the sword dropped from a random mob on Isle of Thunder as it fit very well with his style. I still wish I could find a better looking chest piece that has less green/gold mixed in it, alas none exist to fit the theme much better than that one.
Imperitus @ Khadgar, I can say with confidence, has put together a set that will go down as my favorite warlock set, to date.
A lot of sets come together nicely, but this set looks as if it was designed specifically as a tier, through and through. Probably one of the most complete sets, of any armor type, that I've seen. Excellent work! :p
