In one of the recent topics “ Battle Pass in a new format!” I’ve asked TheLucky about whats happening to the Gold Orders which can be acquired in daily boxes every 15th day. He replied that, they are thinking about it, however they will be probably replaced by weapon/soldier/vehicle upgrade order. Also someone on the RU forum asked what’s gonna happen to achievements which give Gold Order as a reward, to which James said that they are thinking about what to replace them with.
My suggestion
If developers will move on with their suggested changes and removal of gold orders from the game, I suggest that all gold orders which can be acquired in the daily boxes and rewards for the achievement should be replaced with a random gold order weapon from past Battle Passes.
