As I think someone else stated, a more interesting path for the story would be for the companions you passed on to resurface later, as enemies or just npcs (ideally, to a greater extent than was done in DOS2). Without a story line that supports it, having all the characters at your beck and call makes them shallow. At least in DAI, for example, you are the “chosen one” or whatever (a grossly hackneyed premise by now), so I guess the idea of all the unused companions just hanging around home base isn’t completely ridiculous. So far in BG3, though,it seems the main player isn’t any more special than any of the other characters. So why would they hang around waiting for you to throw them a bone?
