For me, I actually don't mind at all if different dialogue options lead to the same outcome. So log as there are still a couple different outcomes I actually prefer that. It means I can make my character varied in the reasoning and responses to different events, it makes me feel like my character has an internal life, like they have complexity of their own. In my first run I enjoyed being able to play a prideful, openly dismissive heretic and then changing tack and playing more lip service to the Imperium for the sake of hiding my plans. I felt as though I was able to make and play a character who was actually complex and a character in their own right, while after a while I felt disconnected to my Tav and now I feel that Tavs are just a vehicle for messing around with the story rather than actually a character able to express any sort of internality.
That's where the roleplay in BG3 falls flat for me. To me being able to have lots of varied reactions voicing my character's thoughts is more important than gameplay stuff. I like being able to give my characters unique arcs and development even hour I generally go down he same story paths.
