The question remains. Why go out of their way, add new voice lines, cut scene and all that, instead of just adding one quest and two lines of dialogue at the end? Even if it would take longer than 2 weeks or whatever they needed for patch 2, just do that instead of the whole "ending she deserves" bullshit
Giving her a proper ending will take months of work. Her quest essentially ends at the start of Act 2 right now (and by "end", I mean you're just told there is no fix and that's it, you're then given the opportunity to trade all those infernal irons you've collected for gear, lol). Expanding her quest beyond that would require tying it into existing Act 2 and 3 quest branches, which is complicated.
I hope she gets a proper, finished story one day (I'm assuming there will be a definitive edition at some point withing the next ~12 months). I really want to do a Karlach origin playthrough, but there is no point right now.
We could have waited if Larian had given us at least a hint that we COULD expect Karlach's quest line to be improved and corrected and given a good ending like ANY other character. Unfortunately, Larian apparently prefers to remain silent, Sven Vincke left the project, new dialogues turned the once cheerful and optimistic Karlach into a cancer patient in the fourth stage who no longer wants to live. Unfortunately, we have no confidence that Karlach will not remain as it is now even in the Definitive Edition.
You can't expect the devs to respond to every piece of feedback. They reworked huge parts of DOS2 without ever indicating they would.
And if Larian doesn't ever finish Karlach's story (which I doubt will be the case), then modders should be able to do it.
