Here is my feedback, that probably help to make Book III better. Sorry if this issues are already discussed or I miss something.
1. Playing Book I and II, I constantly used a kind of 'bug' (feature, if you would like


2. Foraging skill is too good. Having quite high level of the skill, you get almost infinite source of money. Just through camping, gathering reagents and selling them.
3. Combat mage are too strong, comparing with other characters. They do more damage than pure STR-based characters. I think, you know about it) I just hope, that characters will be more balanced in Book III.
