The lead writer and Sven is wrong. What they didn't anticipate is how popular Karlach would become + no one is buying their reasons ( which I would call it lies ) that Karlach ending was not cut. The removal of upper city made act 3 bad. All the quests in Act 3 seems half baked. It is quite telling in the difference of quality.
If anything, they now must consider doing making an ending for Karlach and restore the upper city. Most people would disagree with me, but Baldar Gate 3 is a 2/3 finished product. The last 1/3 is still badly done and from my personal view, Larian winning game of the year shows the quality of competition there is, rather than the quality of the game.
I do find problem with lead writer reasoning that the whole theme is what you would give to save the world because the possibilities of not becoming a mindflayer were always there, but the game bend your arms to make a choice you could avoid. Perhaps it is time to find better writers who doesn't force arm players.
