Hello, Larian!
Let me give my humble opinion.

Mages have a huge number of spells that they can use in battle, respectively, they also have a lot of variations of actions each turn.
But non-casters are limited to very few and uninteresting abilities. I know that you are bound by the rules of the board game, but if you decide to add more active skills to non-casters, I will be very grateful. A variety of abilities is a variety in the gameplay.
You did a great job of making the warriors interesting in Divinity. They had diverse and numerous abilities.

Thank you for reading!
I'm really looking forward to your game.
