why no more chromas for BE

just as the title and says AND when do you think they will bring it back. I only unlocked like 10 chromas so far cuz they cost so much but i still want to unlock all of them since it's free. I dont have to pay, i just use my BE but idk if it's just for now or they will bring it back in season 8 forever cuz it makes no sense to just take it out.
