I mean, I don't look at the current female companions as bitches at all. I'm actually really happy that Larian didn't go the "aren't I just the cutest and most innocent princess ever" route with them.
It's a tough world and the companions are in a tough situation. The standard tropey naive and optimistic girl would feel out of place. They have no reason to trust you and they're on a serious quest with their lives on the line. Flowery anime-esque "uwu" conversations wouldn't really fit the narrative or the style in this circumstance. Strong women aren't for everyone, and maybe JRPGs are more your speed if you really need the presence of oblivious, dramatic, and insecure female characters to enjoy yourself.
Besides, Lae'zel and Shadowheart start shedding some of that steely exterior over the course of your adventures together. I don't see the issue at all and I love their personalities.
