How about some Crafting/Gathering dungeons? Where you would gather high yield, high quality items with friends and avoid getting killed by monsters using stealth and being "crafty".

Or take on massive projects that would require the coordination of multiple crafters across different disciplines to complete a massive item; Such as Airships, Water/Underwatercrafts, Unique Mounts and Gigantic Machines of War (possibly for PVP).

Also for participating in and completing these dungeons/projects you would get additional recipes for more advance craftable items, possibly craft HQ gear that comes close to raid gear quality. Being a crafter/gatherer does not just have to be about making money it can really be something even more amazing than it already is.

One last thing, how about some specialized retainers with MASSIVE amounts of space just for crafting materials. Imagine the possibilities
