While I appreciate the effort to clarify how the system works, DICE is ultimately still locking gameplay-affecting items behind lootboxes. One player may not be able to unlock and equip the best cards right off the bat, but those who invest money into the system are still going to be able to gain an advantage, however slight it may be. And what's worse, if I put money into that system, there's no guarantee I'd even get the same cards. That just doesn't sit right with me. While I understand we're just over a month from launch and it's likely unfeasible for DICE to upend their entire progression system, I really wish these boxes had just been cosmetic only.
For now, unless I absolutely must play the campaign, I'll probably be cancelling my pre-order. I'll hold off for now in hopes they address this further/put out another beta to show the changes, but at this point I feel like I should wait for a significant discount.
