First, associate design director Dennis Brannvall confirmed on Twitter that, like the 2015 game, Battlefront II will make use of dedicated servers for multiplayer. He also said that the new class system for Battlefront II will not offer the same level of "freedom" as the Star Card system in the 2015 title. However, Brannvall stressed that, "You can definitely customize your trooper class quite drastically to suit your playstyle."
Additionally, he touched on the reloading system for Battlefront II. Without giving away specifics, he said it will be a combination of cooldown and reloading, "kind of [sic]."
"We're doing some improvements and we'll have more details later," he said.
We also learn from game designer Christian Johannesen that Battlefront II's $80 Elite Trooper Deluxe Edition content--at least some of it--can be unlocked through normal gameplay. As announced previously, some of this content includes "upgraded" abilities for every Trooper class: Officer, Assault, Heavy, and Specialist.
