Perhaps create a split when you create your character ,you can choose between focusing on the workshop or Farming.
Both options having exploring the world for materials to complete your quests
Except with farming your foraging for seeds and parts to build farm machinery
Have 2 sides in what is now the builders guild one for building quests and one for farming quests
You could even have a 3rd option of hybrid game play where you do a bit of both farming and building like making machines for automated farming
also I'd love to see some what steampunk type farm machinery
