How about a repeatable crafting or exploration quest where you can get extra items from after completing the main 3-tier crafting prompt? Once a month or every other month seems fair for the active folks! It would be a nice way to accrue more materials, especially since after you finish the main set, you really can’t get any materials through quests anymore.
General statement: it’s very difficult to purchase things in-game when there is very little that is providing currency! Especially if you have a low character count and don’t have any more quests to do! We didn’t get any income on the mini winter event, and after a stale year, there really isn’t much. More repeatable quests in general would be really helpful for those folks, and definitely encourage more participation I feel!
