I have the same concerns as Uncle Lester's spoiler.
I want scowling Shadowheart back and I want to her break off the relationship with the MC only to start it again. Just like the Viconia romance. This should be part of her redemption -- Shar is goddess of loss and sorrow. New hope and new beginnings should invoke a crisis of faith.
While I normally agree with Kanisatha I did like Durance exactly because he was going through a crisis of faith. I wanted to help him understand that he was serving a goddess that used him like a tool to be discarded when he was no longer fit for purpose. Durance never became 'good' because 'good' doesn't exist in PoE but I enjoyed bringing him to the point that he would denounce Magran.
So far I like old Shadowheart and current Wyll the best.
I also agree totally with @Uncle Lester's spoiler-hidden observation, and for exactly his implied reason.
But @KillerRabbit your point about Durance is a good one, and I agree with it. I did like the crisis of faith story part of Durance. But his type of acerbic/caustic personality is just something that grates on me too much these days. So, liked his story, but hated his personality.
