I figured I'd post to keep the thread alive. Normally I just check the site and see if there's any news. If you're reading this Larian, I put my playthrough with Karlach on hold simply because of the ending. I'm still holding out hope there will be a happy ending at some point.
I do believe the fact that people, me included, are refusing to finish the game because of a character's ending should be of concern for Larian. Hopefully they agree.
Edit. I gotta love these forums, had to clean up like 10 copies of this same message due to a gateway error <3
