Came across a cool thread on reddit today (yes Randl, it is good for more than porn) that an artist posted with minimalist/graphic images for all of the class/spec combo's.
Imgur Link
Reddit Thread Link
And a couple sample images I thought were pretty good




Also now looks like the guy is setting up a shop for t-shirts and stuff with some of the images, link is in the reddit thread comments.

Enjoy
