Another thing that should probably be re-instated is everything just after Poe says “This is how he finishes it”. Yes, the planet-killing part 100% needs to go, but there are some other critical parts here.
So the scene immediately after Palpatine’s holo meeting with Pryde would start with Rose saying “Listen, it’s on every channel.” I think the scene is important because it tells us that Leia made Poe acting general. In original Ascendant, it isn’t completely clear why Poe would be next in command. There are technically several others who have more seniority like Commander D’Acy and even those who might be more fit for it like Connix given what we learn about Poe’s background in this movie. I think it’s important to emphasize that he was Leia’s pick despite all of that, kinda like how she still trains Rey despite her dark potential. Furthermore, the scene gives us a better reason for all of the civilian fleet showing up besides Lando knowing trillions of people and Leia negotiating with some planetary leaders. If everybody on the HoloNet hears an ominous message like that, they’d definitely be much more willing to rally together.
