I'm glad to see that I'm not the only one with this opinion, and I believe you're right. We won't see a better/happy ending for quite some time assuming one will be added. But, that's fine, I can wait. Karlach's endings are some of my only gripes with the game. I'm still in act 1 after 90 hours and stopped playing after her endings were spoiled. Which may be stupid but I can't play knowing her current options. I got the impression progressing through her quest that the engine would eventually be fixed, but to my understanding it's just a fetch quest that's doomed to fail from the beginning and it doesn't sit well with me.
