There are too many loose ends that she's a long way from wrapping it up without it feeling rushed. What she needs to do, in my opinion, is change her writing method because clearly the gardener method isn't working, or should I say, isn't providing expedient results. Maybe if she switched to a more architect method approach, clear roadmaps of development would be in place, and she wouldn't keep banging her head against a wall every time there is a new chapter to write. It would make less sense the further you are along, but considering we are probably halfway to 3/4 in development, it might still be worth it. Also, not caving into the whims to rewriting would probably help as well.
