Extremely disappointed by the lack of content for Minthara in Act 3. Once you get there she is basically a glorified hireling.
For example she barely reacts to Orin's presence when she's the one who bullied her into joining the Absolute cult
Even while romancing her with exceptional approval, you can only ask her her opinion about other companions or tell her to go to camp. Now i'm reading on reddit thats she is missing some 2000 lines of dialogue and her extra content might be cut for good ? If that's true, i can only hope Larian reconsiders, and we get the Karlach treatment (as in, she gets more fleshed out and a proper ending in a future patch). She is by far the most interesting companion in my opinion story-wise and deserves much more than what she's getting now.

I will add a spoiler on the matter :

Currently she is the only good reason to side with the goblins, a decision that costs you 3 companions (Karlach, Wyll, Halsin). The other option i believe is to steal the idol of Silvanus, which deprives you from several Tiefling related quests and arguably one of the best item in the game (Potent robe) . Either way that feels really, really bad.
