They did this with the anima relics
Remember at the start of them there was a step that was like “ask people in game for how to obtain these items”. Well one of the multiple methods was crafting (diadem was another as was extremes and one of two others I can’t remember)
People hated the idea at the time because old crafting was a complete nightmare (anyone remember whistle while you work) but I think it would go down okay now even though we have crafter relics. Though the popularity of crafting is still debatable
