It would be nice if Lae was more precise and pragmatic in her hostility. Especially in the sense that she'd be more conscious of the fact that she's not among her own people, and that she has to rely on foreigners, even if she regards them as tools.
Her unwillingness to let you handle things when it's prudent (like letting you ask about the gith patrol from the tiefling before resorting to threats of violence) imo just seems careless and undisciplined even when taking into account theviolent gith culture. But this type of reckless behavior, that doesn't take into account where you are and with who, is rather commonplace in the game, and something we see also in interactions with non-evil NPCs. So it's probably more of an overall problem with the writing and not just a character spesific problem. Devs also seem keen on constructing some sort of detailed traumatic background/present for most of the evil characters to account for their misdeeds, which means there's no short supply of volatile/foolish evil types like Kagha, Shadowheart, Lae, Kethric etc. It would be nice, if we had other alignments than reactive stupid evil.
Given that the gith culture is essentially a racist and genocidal religious warrior cult, that devours even its own top dogs, I think she'd be more interesting if she didn't so fanatically(and cluelessly?) align with the sacrificial ideals of gith society. I suppose this wouldn't matter so much in interactions with her, if you could have antagonistic, rock bottom approval relationships with party members, like in Dragon age 2, especially since mocking her beliefs is kind of fun. Still, even if you're obliged to let her run amok, at least Lae has a personality, is possibly easier to "cure" from her origin backstory, than say Shadowheart, and she doesn't approve of the idiotic brainworm farming plotline.
As a romance option she's passable from a D/s perspective, but she doesn't differ that much from the standard skewed/retrograde way kink is depicted in games: yet another self-destructive evil dominant woman in a game that mostly equates kink with the insane and the (oft. non-consensually)hierarchical evil.
