Interesting, in this set of companions two of three men are polite and not aggressive, instead the two women are harsh, and suddendly it seems that there are no likeable companions, further more the man toon has dialogue options that range from very polite and friendly to aggressive, that is where it counts you can decide how your toon that supposedly, being this a ROLE PLAYING game have their own characters and likes and dislikes.

I myself are very polite and friendly a bit shy, I played a toon with that likelihood now I'm creating a character that will be harsh and non friendly (and that will fall under the charms of Astarion).

Furthermore I don't see, made an exception for Astarion who is really arrogant, arrogance. Lae'zel is a skilled trained warrior from a very intollerant and violent race, she acts exactly that way, didn't saw any hint of arrogance in Shadowheart, Wyll and Gale like to gloat and boast their past actions but when you talk with them they show enough humility to openly accept their own bias and fallouts and how they screwed up in their lives.

Maybe the problem is not with the current companions but with two of them.
