In the future there could be some sort of skill leveling system for things like crafting,mining,monster killing and etc. When we level these types of skills then when we reach a certain skill level we could unlock achievements,items,exp and more. For achievements you could unlock something called Craftlord when you reach level 50 or 100 on your crafting skill level or you could get some exp that could for your normal levels.
Also idk if i posted in the right topic because i have no clue sorry
Harvesting leveling will be in the next patch.
