Why are you so concerned about min-maxing and shooting yourself in the foot? The game difficulty doesn't require you to run optimized party. You can complete D:OS2 with all kinds of parties if you don't play on the highest difficulty. This is a single player role playing game. Not a competitive first person shooter or moba. Whats the point of playing with the "best" party? If you want the game to be easy, just lower the difficulty?
