I mean most companions do have a second romance phase towards the end of the game, so they mention reactivity but surely there's more missing there. I'd imagine some of that will be part of the fixed content.
They might. But nothing in this blog post indicates that they will.
I don't doubt they're working on that. Even if it's not all done in the next patch I think they recognize Minthara is quite popular and a lot of people are quite miffed by the missing content.
They recognized it pretty fast in Early Access. They pitched her like the reward for taking the less traveled (and very punishing in terms of what you lose) path; which given how she's kind of just been a wall flower after rescuing her for most people talking about it has been pretty grotesque. It's weird that almost none of her specific content was functional in the final release to begin with, considering she was intended to be a companion long before Halsin whose content seems as polished as any. It wasn't a good sign, and while I recognize progression blocking bugs were a higher priority, leaving her non-functional while they smooth out reactivity flow for dialogue that isn't even accessible yet has made it even more weird. The writers knocked it out of the park with her development even with what little has been working properly, and moreso with what precious little was fixed in Patch 1. So here's hoping we don't get short-changed with whatever they consider to be her intended state because she's hands-down one of the best-written characters in the game.
Likewise with Karlach, I hope her expanded epilogue includes completing her quest development with the items and options clearly intended to earn her a happy(ier?) ending that just kinda sit there doing nothing as-is, and not just one more branch of dialogue to choose. Personally I'm good with tragedies, but her quest just tapers off and doesn't let you use the stuff that's clearly meant to continue it. There are even characters that should have been able to allow her quest to progress (though perhaps more definitively in a tragic direction) if Dammon was rendered unavailable, but instead her quest just gets stuck. There are some weird gaps that need filling in the longer-term than I think the next couple patches will get around to.
More directly to Larian: I get why you guys may have been apprehensive about the ending starting to take a little too long to wrap, but you made that content for a reason, right? It's what people want from this specific genre. So I'm glad you're acknowledging people want it hooked back in and if nothing else I hope it at least makes the people who made those scenes happy that they'll actually be seen and appreciated.
