I think it would be great if there were some really hard recipes that needed you to farm extremely rare drops around Eorzera to craft gear with a really high crafting level. This would encourage teamwork, activate the dead economy and most importantly create content that players can complete in their own way without arrow markers spoiling the fun of discovery.
Also this would be really cheap way to add content that is optional, challenging and makes the population a bit more interested in exploring the secrets of this game.
