In my opinion, this should be handled like the latest string of Marvel-based superhero movies. There were individual movies for Iron Man, Thor, Captain America, etc. to introduce the characters and their back stories. Then they got together for a big "group saving the world" conflict in the Avengers. Now they are going back to separate movies to progress each character individually a bit based on their latest experiences (dealing with their latest place in life). Eventually there will be another Avenger movie with the group to save the world again.
Alternating back and forth makes sense to me. Going only with the group from now on seems to leave a lot of personal issues unresolved for each of the characters (like what does it mean now to be a Darth for the Inquisitor, or to be the Wrath, or to own the underworld, etc.?).
