Really? This has to be the laziest, last second art I've seen since Cata. All the mounts/armor since Cata (when Blizz seemingly got a new art team as the quality of models changed drastically) have had a lot of detail and you could really tell the time invested in each.
This is a horrible re-skin of the amazing rated BG's wolf. Essentially "strip armor detail off, and insert spikes.... lots of spikes. Head armor? spikes. Paw armor? Spikes. Yes, excellent, very spiky. Wait! YES, GENIUS, PUT GIANT SPIKES ON THE SIDES LIKE THE AMANI WAR BEAR! Now it is perfect!" Just look at the skeletal horse and nightsaber mounts they just released, much more what we've come to expect.
Disappointed blizz, disappointed.
