you probably ought to play more of kingmaker.
i actually dont think Amiri or valeria are particular bad.
Amiri obviously carries a grudge, but shes also a paizo character. you can also tell her to stfu.

Valeria also gets (unless you cheese it hard) bitchslapt by her former mentor and eventually develops a bit of a better perception of things after getting the scar.
the only thing in that regard pathfinder has is the whole threesome relationship thing, but its not like that isnt shown to not work out at all when you meet the characters.
So eh.

I know a lot of people like to shit on owlcats characters, but most "flaws" these characters have are not meant to be endorsements, they are meant to be flaws, which is what makes characters interresting and non static
