One of my main complaints so far is that other party members seldomly pipe in during convos. I get why they didn't do it more, as the game is massive with already a sheer amount of dialogue, but it makes my party feel kinda flat. Like sure they do little quips or remarks while walking around, but even those aren't very frequent. Maybe it changes further into the game, but I'm about 35 hours in and done almost everything in act 1 so far. I'll be thrilled if this changes in later acts!
