I think this is the best way for them to incorporate a Karlach good ending, since most importantly, it's hard. We can have the Karlach dies and return to Avernus be the default endings, and have this be the secret good ending which both adds player agency in her story and gives her an almost secret questline. You can also have the conversation with Barcus about doing something about Karlach's engine after you kill Gortash so we get her monologue, and THEN the catharsis of our hard work being rewarded with a good ending.
Not to mention, this is what we all originally assumed was going to happen the first time we went through the game, it felt only natural to have it at the end of this mix of questchains
Yep, I was one of the rare souls that didn't actively look for spoilers or guides and spent so much time trying to find anything for Karlach in act3. I thought, maybe I missed something, maybe it's a secret thing and I basically explored every corner of the map. Nothing. So I decided
to pay a visit to Gortash - my naive brain thought something could surely trigger after it.
Well. Imagine my disappointment when i found out in the journal that was all for her. It felt so empty, so unrewarding, so frustrating. And after all that, I googled to be 100% sure I didn't miss anything in act 1 or 2 only to find out this is how her story ends.
Feel sorry for those who googled before finishing their game and the results killed their mood to continue.
Oh for sure, i never google anything before finishing my first run. As you did, i spent my sweet time in act 3 and at one point i was convinced i had missed something crucial in the previous acts. When the credits rolled that's when i started googlin and discovered this forum/thread, where my sadness began ahah.
