I'm with you on this one. The aesthetically pleasing weapons for Dancer are really lacking, imo. When they added the Thordan EX crafted weapons I got a little excited, but then they didn't add any others for us. Just disappointing. There's no explanation as to why we got a Shinryu weapon and no others, either.
I realize we're not alone in this- GNB is in the same boat, and SGE and RPR are way worse off than us. I was hoping we'd at least get Titania or Innocence weapons sometime soon, since we got Hades in one of the later patches of ShB, but I'm losing hope. I just want a bigger selection of sparkly weapons than what we currently have. ;-;
