I only have one example atm because it just happed again. When you find Withermoor´s soul jar and want to destroy it, your party has their own opinions about it. What I think is really strange, is that you have to be the one talking for your party... it makes me feel like having four conscious. Since your party members have their own background it is wired to talk for them.
For me it would be logical that they say what their background and personality calls for. Then what I do should effect how they like/ treat me.
This happend more often but as I said, I only have this example now.
Hope I did explain it so you understand :) sry english is not my main language :/
