I personally think we should be able to purchase Scion Weapon Camos or get them as gifts from the Scion trainer(s) as long as we get the required number of retweets and shares.
I really want more copies of Luchs Frieden and the Phantom and Etoile weapon camos for my alts to use. Even if it cost Ex-Cubes, Photon Spheres, or a chunk of meseta per camo I'd be okay with it. They aren't able to be traded or sold on player shops so I feel like getting them from a special NPC or shop would be okay.
Also, my CASTs are excited for the Etoile CAST set, and my Human and Deuman are gonna love the Phantom's outfit/layer-wear. I only hope the people rolling the scratches for them get enough to keep the prices affordable for my budget self.
