It's an easy little interface, and you can very easily see any of the armor sets (and all of their variants, which makes me think that it might be cool if the different spec variants actually looked, y'know, different) on any race, and even any gender of your choice. Gaze at the beauty of the Skyshatter set! Be in awe of the Warlock's Malefic armor! And puzzle why Paladins got yet another strange-looking armor set. Blizzard should just put ballerina gowns on them next time and be done with it.
