Neverar - Very fascinating concept of breaking things up. The mockup video had some good ideas and I would agree with Hal its ok to be away from Rey a bit. Hmmmm. Obviously from your list and parts of the mockup video one of the obvious issues is the who helmet and pacing for Ren being off and on like crazy. 😉
For Hal, that alternate solution can work since it now gives a reason to target the resistance since their main objective has been completed … time for the next one.
