I definitely got to the stage where people should have been giving approval but didn't, and then instances where I'd get a 'slight disapproval' which would let them approve again after (so I'm assuming there is a max but it doesn't stick there like in DA2?)

I let Morrigan do it last time, and I think I had Blackwall, Cassandra and Solas in my party. So disapproval!town. I think everyone comments on it if you ask for opinions. But I think it's weird how non-party members who might approve/disapprove of what you did when you get back to Skyhold seem strangely random?
