I romanced Astarion and did his spawn ending and I thought his ending scene was fine. The only thing I would change is adding a line from one of the recruitable non-origin characters about checking on him. I honestly just assumed it was one of those "you have to go through it alone" moments for him.
Lae'zel, Karlach, Wyll, and Gale still have some pretty huge character-defining moments left and I liked how the game emphasized them in those moments.
