As a possible, workable idea for future patches, aside from the signature of the crafter in the stats of the item, I think it'd be nice if master crafters (sorry, only those who've hit that point) can create an individualized logo that can be placed upon their masterworks as a visual signature of their work.

As an alternative, much like FCs can have a crest on their gear, perhaps establishing "Trading Companies" that can brand their gear would be rather nice as well. One of the plus sides is that it would essentially promote craftwork alliances among players, beyond what linkshells or current systems permit. As a mild downside, it would be obvious if your gear is bought and resold at a higher price (which is rather underhanded anyways).

To go along with this idea, I would of course want to see more gear recipes, both vanity and otherwise. What are your thoughts?
