[UPDATE] DICE executive producer John Wasilczyk released a statement on Battlefront II's controversial loot box/microtransaction system today. He explained that change will be a constant for Battlefront II as it pertains to changing the in-game economy, with tweaks coming as DICE considers and responds to player feedback.

Specifically, Wasilczyk said DICE is aware of the feedback that it takes too long to unlock heroes like Luke Skywalker and Darth Vader. "Unlocking a hero is a great accomplishment in the game, something we want players to have fun earning. We used data from the beta to help set those levels, but it’s clear that more changes were needed," he explained.
