Now, this doesn't actually mean that Blizzard is lying to us-- maybe one of their staffers had to get the armor set in, and accidentally used the small shoulder art. But it does at least tell us that Blizzard's right hand isn't talking to their left. And it does give just a little more credence to the conspiracy theorists among us-- why were the shoulders changed in the first place? Is Blizzard trying to stealth nerf those gigantic Orc shoulders?
Admittedly, it's not a huge deal (unless you're a male Orc and extremely proud of your larger than life shoulder armor). But you do have to wonder why Blizzard is being so skittish about this-- are they actually trying to make changes to the art that players just don't agree with? And if it is just a bug, why hasn't it been fixed yet?
