Having a group of four and the rest of the companions sitting around in camp felt a bit weird in BG 3. Especially if the companion stories were closely related to main story events. I always felt a bit uncomfortable to not have certain companions with me at certain stages, although I actually did not want to have them in my group. Lae'zel, Karlach or Wyll for example.

I hope for a bit less condensed and hasted story in Divinity, so that companion stories could be a kind of side story, without you feeling that you absolutely waste time to do this and that instead of pushing the main task. The companions not in the group then could be imagined to do their things, and the whole bunch meets in camp to share experiences. Maybe one or two further companions could accompany the party for some of the tasks of the personal story, without being playable. That's also easier to balance.
