I should have asked if the party being locked after Act I would change whether or not you'll play as Tav.
Not for me, though I do still very much hope that the party won’t be locked after act 1. I’m not sure whether there’s been any more recent reconfirmation, and if not I’m going to keep my fingers crossed Larian have thought the better of that idea.
I do think it might be fun if companions would go off and do stuff without you if they’re not in the party later in the game, but would still rejoin you if they were free and had a high enough attitude. I can’t currently envisage any plot contrivance that rules out all but three party members at the end of act 1 being remotely satisfying.
