forgive me if this has been suggested somewhere already.
It would be pretty nice if there was somewhere you could craft UVs for a premium. Not craft weapons with a chance at UVs but randomly craft the UVs themselves, and then they could be combined to weapons or armors of your choice. Again, this would require a considerable amount of Energy/Crowns/Mats, but it'd be a good "sink" and one that people would use like crazy.
Weather or not the UVs came bound or not, well, that could be to the dev's
