To jump into Brint/Brienne discussion that was happening earlier in terms of personality I really didn't see them changing much outside of becoming submissive and hyper focused on the champion. I do wish the whole Mad Cow quest potentially gets a rewrite because telling him we'll go to see Sanders then just avoiding Sanders for a couple of days just... was jarring. I think it should be handled through omission instead, I think the demon Viv path was a good example of how to do this. I didn't feel like I was really forcing Viv to become a demon in that path, it's just the champion thought it wasn't too important to mention, that "Viv's a big girl she'll figure it out" mentality is what I got from it. I think Brienne should have been handled the same way, but again it's older content and hindsight is 20/20.
Instead it would have been neat to have the option to reach out to Lady Evergreen or Viv and have them look. Explain that the effect the armor is having isn't malevolent, maybe give some lore about other enchanting armor changing something about the wearer to provide a boon and have Brint decide to wait it out to see what happens instead of going to Sanders. That would have been a much better way to handle the quest.
