Trying to put a positive spin on this:
As Tav i have NO BAGGAGE (except for being abducted by mindflayers and implanted with a tadpole), which makes me unique among all companions and Durge. So i can be sth like a mediator between my party members.
Don't know it that is satisfying enough, depends on how the story plays out as a whole. We'll just have to wait and see i guess.
