The difference, which matters to me between BG2 and D:OS2, that if something goes wrong in BG2 I would try the encounter again and try something different. I could retry the same encounter multipletimes, with the same party composition and attempt to solve it in multitude of ways. That's also the memory I have of D:OS1. Not so much with D:OS2.
Yeah, not my experience either. I do tend to play it with one toon on Tactician, though, or currently with my friends on classic. So maybe I would feel differently with a full party all under my control (I stopped in the middle of Act 3 with a full party on Tactician because it was getting too easy ... that was not Definitive Edition, though).
