I have no clue if this would even be possible, because right now the entire job system is set up to prevent bonuses from and even punish changing between jobs. But wouldn’t it be cool if herbalists got some perk from farming experience? The herbalist would still be available early, but there’d be an interesting decision – do I want to have my herbalist get some bonus, but not be able to respond as quickly right now and level up slower afterwards, or do/will I need my herbalist badly? Also, I like consistency.
Having the herbalist being the start of a medical tree rather than related to the food one makes sense, and isn’t entirely inconsistent given workers know how to pick various wild plants. But something still feels a bit off to me somehow?
