Have a feeling that we'll never see wings unless in Alchemy, Denier Cri or the Cash Shop. And so far, it looks like they've made the animated wings in the forms that have been asked for in this thread.
I wouldn't mind more wings, but if they did a user contest, the items would be put in crosstich, since that's where all user-created items are sold from.
But I think one of the rules of the contests is specifically "no wings", so I don't think that would happen
if they did an item contest, they certainly would not be put in Barton Boutique but rather CrossStitch. aside from that, affordable GS wings would be great! unfortunately, i can't see us getting GS wings in the foreseeable future since, as virgo also said, one of the CS rules is "no wings"
