Instead of demanding her removal, just don't use her.
Why do people feel the need to control how other people play so much. You get to fucking choose tbh, just choose.
If you don't want us to use her because you're not, all I'm saying is, there's no one person special enough even if their mom says so to change the game base on what they alone want. Unless you're specifically making the game.
If you want 6 party members go ahead, if you want 4, go ahead, if you want to solo, GO AHEAD.
Simple as that.
Larian will pull through, don't worry about them not putting enough work into the characters you like. This isn't DoS.
They have more resources to work with here.
Just allow people the freedom to choose.
Because folks like you are so narrow minded and tunnel visioned in what you want, you forget there's others who will be playing too.
