I don’t really care about minor reactivity like what a flaming fist will say to you. More what I’m looking for is character reactions to very major plot developments. Which in some cases are egregiously missing. Major act three spoilers:
For example, when Gortash makes very clear that you are not only a Bhaalspawn, but the fallen chosen of Bhaal, Shadowheart as your romance interest has literally NO reaction to that. No comment. Only Astarion had a reaction when I talked to him about that revelation. That’s a massive oversight, and there should be more reactivity there! And then, when Bhaal kills you when you resist him as Durge, there is literally NO reaction from your companions. And after Withers resurrects you, they all seem quite unemotional, like they’ve been sitting there watching a TV show and comment on it or something. And they only say very basic things like, “oh, I knew you could resist your urges.” They don’t mention that you were just brutally murdered in front of their eyes. So yeah, who cares what minor characters have to say? I just want reactivity from companions at some of the biggest moments of the game! And I truly don’t think that’s too much to ask for.
I feel like whole Durge interactions in underdeveloped, not only in final act but from the beginning. Especially if you choose not to resist urges. Only npcs who react accordingly to durge's plot are Astarion and Jaheira.
I feel that is a general Origin problem. For example I have played both as Astarion and Gale Origin. Karlach's post Gortash rant has not in any way been adapted to either of them. You get the same helpless Tav player dialogue choices (while I am sure they'd have something more insightful to contribute) and she is trying to give survivor's guilt to the the guy who is still very much in danger of exploding himself, or the one who may or may not have just freed himself of his master (depending on when you tackle Cazador).
