Is it supposed to look like a stumpy little pony with a giant head, no body and wings that don't flap? Or is that a bug? I can't find any info stating otherwise but it looks kinda ridiculous!
Like most mounts, it is placeable. When placed, the model renders as an expected normal size, similar to most other horse mounts. The summoned model is tiny in comparison. I bugged it 2.5 months ago, the day Drakkinshard went live. I am certain the bug now resides in the not high priority abyss, and therefore will never be fixed.
