A miner and builder have difficulties that aren't really obvious to an adrenaline pumped fighter. A huge problem is self-hypnosis. The first sign I usually get of a wandering horde is my screen getting covered in blood<snipped for space>

The fix for this is so easy.sitting in your base just crafting 500 shovels isnt exactly fun gameplay though, and that exp should only help you make a better shovel rather than other tools. if crafting was more like say finalfantasy 14 or say dragon quest 11 where you actually have to pay attention and basically do a crafting mini game to make the item, maybe then they could have it give exp again but just clicking a button to craft 500 shovels and then tossing them out as they are being made is not exactly fun gameplay
Diminishing returns on crafting the same item more than once. Maybe 10 or so level 1 stone axes and you're receiving no XP from them. Add an XP bonus to crafting more complicated things and the crafter then has a mini-game of trying to source as many different types of materials and a reason to craft some things they wouldn't bother with otherwise.
