To me the unbalanced party choices are reflected in the weapon selections. Laezel is locked in on a great sword per background and fighting style.The rest are dexterity based or spell slingers. There are no NPCs to make use of all of the interesting variety of strength based weapons that you find. That leaves the PC to make a strength based character if you want to experience the variety of weapons and fighting styles. But as the face of the party, I want to be more than a fighter. Having more strength based NPCs would really open up the options.
