SInce the crafting revamp is cancelled, it would be cool if you could add new recipes to the old system. The old system isn’t that bad, it just require some new recipes. This doesn’t require a lot of development resources either. Saga server have brought back a lot of players, and there is many players that do enjoy crafting and resource gathering when they play MMO’s.
Add new recipes that will make crafting relevant at level 80 and it would add a whole new dimension to the game.
It would also be cool if you could add a special saga quest for leveling up crafting professions and building a guild city with unique rewards.
