I find all the party members insufferable. I change their classes almost immediately for better synergy or I switch them out for the soulless NPC's Withers has. Ironically, I've been D&D 5E Dungeon Master numerous times and I find the party members to be absolutely authentic characters real people would play. Good work Larian, ya made the characters so table top believable that I want to find a new group to play with.
