I like the idea of female companions or companions in general that doesn't just readily accept whatever the player character does and turn a blind eye to them. I like the idea of companions that stand up to the player character and questions them on their choices and not follow the player blindly.
Male characters are capable of having opinions and voicing displeasure or dissatisfaction, but unlike Lae'zel, they are capable of acting like teammates, or, at least, can be civil.
I keep seeing people saying we get evil first so expect them to be abrasive and unlikable. The best evil people are super charming. They're just selfish. Astarion is actually a great example of this. Shadowheart isn't even really that evil, and seems to be evil despite herself frankly, and I'm guessing the story will explain that in such a way that she isn't even bad. Nonetheless, Laezel makes perfect sense to me. I mean look at the other Githyanki we meet. Damn!
I would be fine with them being coarse at first and gradually trusting the player, it just seems jarring to me that they never let up. The closest thing between the two of them we have to companionship is SH's sarcasm/jokes.
Sure, it's just Act 1, but let's imagine that these were actual people; how long would they all put up with Lae'zel before just killing/leaving her and finding their own way? Seems the story is able to go on fine without her.
Hell, maybe if we got a way to push it a little? Like, provoke/tease them. At least if they're going to be unfriendly and scathing, let us have fun with it.
