Good idea... come to think of it, it would be interesting if they made content along these lines that involves all crafters (it could sort've be their exclusive "end-game" since working them into actual combat encounters has apparently proven too difficult/possibly gimmicky).

For instance, they could involve crafters in the building of new towns and garrisons expanding into Eorzea through special repeatable leves for certain-ranked crafters, or by making untradeable/unique materials to be given to NPCs.
