The persisting problem that is still being discussed in regards to the "good" endings is how arbitrary they feel compared to the rest of the game.
If Larian is still considering adding to the endings, please add a third option to
convince Orpheus and The Emperor to work together. In addition, for Orpheus, add the option to allow Omeluum to make the "sacrifice", him already being an illithid, providing Omeluum is alive and present in Baldur's Gate.
I have more extended thoughts in a previous post I made
