I feel like once you have a pretty solid list of things you’ll need to edit/add vfx to for TLJ, it might be worth considering if it is worth the work, or if there other changes that might be better served that you could put the same time/resources into. It just seems like a lot of work, and there might be other changes in the film that might be more worth the trouble.

I dunno. If I were to vote on a side, I would say keep the fight. I know there are a lot of weird things about the scene, like why were Phasma and the other troopers across the room, how did they survive and most of the stormtroopers did, when did BB8 learn how to drive an ATST, etc etc, but I feel we were teased with this cool Phasma character and we should at least the one cool fight we got with her, and it isn’t that long honestly.

I would find it preferable to keep her in TLJ, and then roto her out of like two shots in TFA to make her not be the one to turn off the shields, so her arc is less of a mess. Phasma represented something to Finn in TFA, and defeating her as a rebel in TLJ serves his character I think.

My two cents, but it really isn’t a big issue compared to some other moments in the film. Like other vfx I think would be worth considering would be to have the Resistance jumping from system to system rather than go in a straight line, or having the First Order Canon firing as soon as Rose & Finn get out of the way. Just some thoughts though!
