I was watching one of Wooden Potatoes videos (LOVE watching them!) and I noticed something familiar during his Glint video. Towards the end you see an enemy mounted on a creature, who is then defeated and falls off said mount. I paused the video then returned to the scene because I was sure I'd seen the creature before. It took me a minute or two but then it hit me, Utopia was said to have mounts. I Googled the image and sure enough, there it was. Tbh, there really wasn't a lot that was changed about it, and even the rider was using the same weapon in the original art.
The head is altered but the resemblance is pretty hard to dismiss. Stance of the creature, number of claws on limbs and a lance for the rider. Just how far did Utopia really get? Not only that, but the creature is a separate model from the rider. So I guess GW2 really does have a mount, lol.
