A pity they didn't do all this reactivity where it really matters. In quests and coherence in campaign story.
To do something and have no new dialogues, even if the thing you did had a big impact in the story of your MC and your companions is ridiculous.
Other situation is with the linearity of quests. Example: In act 4 you can go right to the arena, finding Sosiel brother, and them free him. Later, if you go to the slave market and speak with the black masked demon with Sosiel in your party, Sosiel start freaking out like the little bitch he is, demanding the demon to say where is his brother. Completely breaks any immersion.
