Just made an account to add my voice to this. Karlach is such a fantastic character and her endings being so constrained is heartbreaking, especially when side by side with how much hope there is for all the other companions. I would love to have another ending available to her. She deserves it.
If another ending isn't in the cards for Karlach, I'd really like to see better pacing and removal of threads in Act 3 that suggest she can be saved. I spent ages crawling up and down the Steel Watch Foundry because there was a dialogue thread that suggested something could be found there. At the very least, that needs to go. Unfinished narrative threads in some video games are... well, never pleasant, but at least not so glaringly obvious as they are in a game like this one, where most others are concluded.
