I think that this sums up my feelings very well too. I am actually stopping all playthroughs at the start of entering the Lower City Currently. This is because if I complete my Durge quest and Astarion's it feels like the emotional investment *ends* because reactivity *ends*. Not just for him, its surprisingly quiet in Act 3, when its literally the denouement and climax of the story. I should be getting yelled at by everyone at every moment, finding companions perhaps taking time to themselves. Anyways its a moot point
Im much more cynical about Larian listening to feedback than most folk, I will admit. Yes the patches are nice good will but the fact that these endings and Act 3 passed QA boggles my damn mind
