Update: Following fan feedback from the game's open beta, EA has announced that it'll be making changes to the loot box and progression system for the final version of Star Wars Battlefront 2. Given the degree of controversy surrounding the system, this is probably an astute move.

The changes aren't monumental but they are significant. Now, more rewards will be earned through play and fewer will come from lucky loot box openings. The highest tier of Star Car has actually been removed from loot crates entirely and will only be unlockable through crafting (a level-locked ability).
