I quite like when characters are judgemental or opposed to Tav or other people based on their personality and background. For me it makes me appreciate them more, because I am not looking for a cheerleader for my character, but a companion with their own personal views and agenda. Some conflicts and dynamics are good for storytelling.
I agree with them being opposed to Tav. I don't mind it either. Actually I kind of like it. I love when they rub against Tav, like Shadowheart and Lea'zel in Act 1. Astarion even though he is my favorite don't always agree with my Tav. Something about Karlach though just don't work for me. She was just a constant nay-sayer at the back of the group.
