14. Luke meets no resistance when leaving Hoth - I know this has been discussed at length and I hope the team do something to address this somehow but I will reaffirm this one also.

Yeh, this was discussed a long time ago. I went through and watched everything in depth to see what could be added, but then realised that nothing needs to be added. The Imperial fleet are long gone by the time Luke and the last few stragglers leave. Vader is after the Falcon and we see that they are pursuing Han & co. Vader and the other ships are there too. Vader isn't bothered about defeating the Rebels but only interested in getting Luke. He knows that capturing the Falcon is the key to ensnaring his son or that Luke may be onboard the Falcon. So Vader and the fleet blockade are gone, enabling Luke's easy escape.
