In their attempts to modernize? Try something new? Everyone has lost a fair amount of weapons, which now require crafting a 5* weapon and upgrading it to unlock specific non 5* weapons as abilities. If you're someone who played constantly, then you should have mats to blow; others, like myself, even with refunded mats, do not enough to re-create the weapons we lost. I really can't rate it any higher than 1* now.
