Given that I couldn't stand any of the currently available companions in EA, it would appear that if I ever played the game again I would be stuck with the remaining 3 companions. That is a stark contract to the previous games where there were probably only a couple of characters I never travelled with.

It was fun to swap out your party members when required and exciting that on first play through you never knew when you were going to meet a potential new companion. In BG3 we meet all companions in a very short period of time.
