Battlefront isn't known for SP campaigns so they can do whatever they want in it really. I also don't think that doing Star Wars: The Line is the proper way to create a good story.
You're just setting yourself up for disappointment if you're expecting yet another story similar to Spec Ops. The writer isn't likely to go down that route yet again, especially with a Star Wars game.
I know, I shouldn't expect it.
But it would just be a lot more interesting if it was about a Imperial soldier after being a hardcore as fuck Empire follower to go:
I know that guy-who-I-forgot-his-name-but-was-in-the-latest-Star-Wars-movie left the Empire but he never seemed into it anyway and was already on shaky grounds. This person teased in the campaign have already in the trailer been going "Impossible!" at the Death Star exploding (even though this is the second time a Death Star explodes so who is fucking surprised at this point?) and "WE WILL AVENGE OUR EMPEROR!!!!!11" so clearly she is deep down that rabbit hole of fanaticism.
Anything really to shake up the usual boring PG-13 Star Wars story. Knights of the Old Republic 2 is so far the only Star Wars media I remember where they actually started to ask questions regarding this whole light vs. dark thing, who is actually evil, who is actually good, does shooting lightning with your fingers really make you a bad person even though you could potentially only be aiming those fingers at actually awful people and not at just newborn babies as the usual Sith characters?
