Machinist: Aetherotransformer doesn't change appearance with weapons

I'm not entirely sure what's going on, but the Aetherotransformer (the ammo box on Machinist hip) that Machinist wear do not change appearance along with the weapon/gun. Not sure if this is just a lazy effort on Square-Enix part or it's intended to be that way. On a bard when they switch weapons their quiver changes looks. The same also applies to an Astrologian where depending on the weapon the card deck changes looks.

I don't understand why it can't change appearances based on the gun that is equipped. Right now the fact that it stays the same is somewhat boring. I feel the job itself has been rushed for release as most if not all the animations are a bit boring. This includes a lot of the gun models.

Please take a look at the Aetherotransformer. There is no reason it shouldn't change appearance like the Bards or Astrologians or any other job.
