Not to wish ill on Battlefront 2, but hopefully this game will get buried by reviewers.
If we are talking about the future of gaming and how lootboxes can affect gameplay, this will be something that is addressed and pointed out for how dumb this decision was. You could say that Shadows of War was the first battle, but you can say that Battlefront 2 is definitely the first major fight of how these "random drops" can affect the overall experience of the game.
As for the score, I would imagine that EA would want to aim for 8s since anything lower could be a tell that "This is your basic game with nothing special," to it; much like the first battlefront game that averaged around 70-75.
