I'm glad to see active on this topic, it gives us a better chance that Larian will pay more attention to the Kagha and make a rework. All the same, she is cute, I would like to romance her in the second playthrough. She is even better than Shadow Heart, but needs to be more neutral and "more elven" albeit with a difficult character. Her features need to be softened a little too, as well as her character, so that she is more cute. But just a little so that she doesn't become too good.
If Larian wants to add more companions and characters for romance, then let it be Kagha and not the strange werewolf halflings or tieflings with a crossbow.
Probably I'm one of those gamers who make decisions on the routes based on what kind of charismatic girl I will get in this route for my party.
