It would be really great if devs are willing to add one new crafting quest per week. It can be a simple quest for a number of ores. Since the higher tier recipes are no longer purchasable, why not add them back in via quests? ie Soltown requires more bronze to make weapons to depend against the undead. Week 1's quest is to gather X copper and Y tin. On completing, the npc quest giver teaches the player bronze ingot recipe. Week 2, multiple bronze ingots to make coil of bronze wire. Week 3, multiple bronze ingots sheets. Week 4, weapons, Week 5 ....etc.... It'll slowly add up and not take up too much of dev's time, while making these recipes available to new players. New casual weekend players can have something new to do every week.
It's not a great market for those drops anyways. Time to scrap that idea and cater to new player growth and systems that make it fun. High end players already have enough ways to earn gold.
