Played a good bit of Kingmaker and while not as refined as WotR I think is very similar. I agree with you that the DoS chaos can be a bit monotone and is too much. But I’d take that over the environmental flatness of other cRPGs.
I think Pathfinder is as bad of a match for Larian as DnD mechanically speaking. Compare the sheer battlefield joy and chaos of DoS to the austere strictness in BG3. And Pathfinder is in the same vein. Better I think it would be if Larian picks up a setting fitting their humour and shenanigans. Heard good things about Discworld.
