Yeah, people- even moderators- can have their own opinions. If someone finds the current endings for Karlach satisfactory, that's their right. Opinions on something like "is this a good story" or "does it end in a satisfying or logical way" are very subjective. Nothing wrong with that. I don't agree- I find the ending of her story utterly unsatisfying, frustrating, and depressing to the point I'm tempted to just let Wyll kill her in chapter 1 even though she's my favourite character in the entire game- but people are allowed to have their own opinions, even if they're not the same as yours. Larian isn't somehow obligated to make changes to it to satisfy people like me that think it's just not very good- though I very much hope they do!
