Well, on that note. I usually give Larian a lot of slack on their writing - but in this instance they rather nailed it: They wrote the companions to their stats [except Halsin].
Wyll isn't physically strong. He is not smart, he is not very wise. Yet, he has heart, which translates into a lot of personality. Not being smart nor wise, he naturally makes poor decisions and doesso in dealing with Mizora.
Now, this is turn may naturally result into my personal gripe - the fact that he has no agency over his own story - he leaves it up to the player entirely. This too, is kind of fair - He doesn't quite trust his own judgment.
