I agree with all those points.
The uncommented notes about the plot bothered me most, when playing Gale's Origin and having Lae'zel in my group. When playing as Gale, discovering what lies at the Heart of the Absolute is your act 2 quest, but it does not update if you find the book that spells out the plot, tells you exactly what the Heart of the Absolute is and introduces the Crown of Karsus to the story. I would have loved to discuss its content with my companions - or at least with Tara. In the same vein, it feels odd that Lae'zel does not react to a document that proofs all her suspicions have been right.
It would be lovely to get a conclusion for Squire. The way I interpret the scene in which she recognises Isobel's scent on you, she is reminded of what life used to be like "before" and stays aways from the fight because of it. It would be lovely to give her story some sort of conclusion - at least have her hang out in the main hall for final farewell.
Many of the long act 1 story arcs are a little wonky in act 3. I would have expected the halfling lady from Ethel's lair to jump in and speak up for us when the gang first meets the other survivors, or get actual intel on how to deliver the missing shipment - in case you take over the job from Rugan (sorry Rugan). I hope that some of these situation will be addressed by the new lines of dialogue that have been promised in the pre-patch notes.
As for Halsin, I was recently talking with someone about him and how the fandom at large seems to see him as this wise and relaxed character, while I can't help to only find him lethargic and a tad incompetent.
