Briefly: "Feel the hatred of TEN THOUSAND MRGLGRGLGLBRGRGL!" This concept for a Heroes of the Storm skin that makes Murky look like Illidan is excellent.
CORRECTION: This post originally misidentified the character art as a skin concept for Murky in Heroes of the Storm. In reality, it's a Blizzcon exclusive pet for World of Warcraft. Chalk it up to wishful thinking on my part!
