Pending when you last looked at them, I can understand that; in earlier alpha versions, they really weren’t worthwhile. In more recent ones, they’ve been gradually improving more and more.
Alternatively, pending how you feel on modding, @Froggy’s Stonehearth Café can really change your view on them.
…herbalists, however, yea, I agree with you about them. I have NOT taken to that class, and much less so since Cleric has come in.
