Rarity is about background, like you have in ships, as I said above 12.7cmverB has black background only, while radar 13 Kai has rainbow if I remember good, so it's like comparing Shimakaze's rarity(rainbow background) with Yayoi and of course thing what can't be crafted are even rarer than their background(so Uzuki or Urakaze is rather raer than Yayoi despite same background). Also Amatsukaze is indeed very rare, but Amatsukaze was prize in the middle of event and Isokaze was last in the event, that's why Amatsukaze is already droppable on maps and Sakawa is not, because it matters which map they were from. Harusame probably will be droppable soon too...
