as a follow up to what your post above - about Act 3
Agree with the Cazador quest, its basically just a dungeon delve which was a bit disappointing.
Referencing something for Astarion to 'cure' him
All you need is Jaheira and a quick conversation. Or she could have left a note for him on his bed that he finds in the epilogue scene - saves having to recall a VA.
Temple Ruins of Amaunator in the Umar Hills in Amn saw a ritual to restore a vampire to true life. Jaheira may have witnessed it or been part of it but she'd certainly know about it- it was part of a quest in BG2: Shadows of Amn
So no immediate quick solution but it could be part of the ending with Asterion, you can trot back and take Cazadors heart and then make plans to travel there. At least it would be something specific, that is known to actually work. It wouldn't be an ending but would set up a continuation and that you have a goal in mind - a bit more hopeful.
Wish spell would be ideal of course
Referencing his Running from the sun
I hated that, it left me so sad. I should have been able to teleport us both out of harms way and comfort him not stand there like a stump. It was in very poor taste and completely unecessary, why have him make the hopeful remark that it looked like the sun not affecting him had stuck and then have this happen literally a few minutes later.(actually due to my first playthrough having Gale make the snippy remark is why Gale gets left in his portal, if I want a Wizard I'll hire a less vocal one). It felt like it was played for laughs and was completely wrong.
Agree completely on the order of who speaks at the dock. I lost reactions from people I cared about due to someone I had interacted with the least (in my case Minsc) taking the first spot.
Astarion specific epilogue ending felt like it was a different writer, it had little to no emotional impact at all unlike earlier scenes with him. was it chucked in at the last minute cos someone remembered there ought to be one?
Also theres a lot of threads on Astarion ending being less than optimal but one of the ones I came across a while back is this one
