I think that one reason why people early on have such trouble surviving is that if you pick some bad skills, there is no way to respec until two-thirds of the way through the game. I think there should be an NPC in the Broken Valley village that can let you perform respecs. (The cost should start lower than 5000 gold, though. Maybe 500 gold.)
I agree that the rewards from treasure troves you have to get by mind-reading and solving puzzles should be of a higher quality than random loot from barrels. Perhaps they always have some amount of gold and one random magical item of some quality, plus some additional completely random stuff.
Divinity III
These suggestions aren't for the expansion, but something to consider in the next stand-alone game:
Bring back some elemental strengths/weaknesses to the combat. After playing Beyond Divinity and seeing its overly complicated system, I can understand why it was scaled back, but it doesn't need to be removed completely. The original system in Divine Divinity was simple enough to understand and use and added some strategy to fighting as a mage.
Bring back some of the other races. The first game had six races represented, even if three of them were almost entirely hostile. But there wasn't even a mention of Dwarves and Lizards in Divinity 2. It would be really nice to see villages and cities which have other races as the majority instead of just humans (humans could also use a bit of diversity, please).
