62 million gil is a lot for one sword. Hopefully they are using it for Gilgamesh or Agrias in the future.
I would wait for Lesalia Guard's Sword which is from a future event. It's +Ice/slash attack and you don't need to craft multiple to +5. Just need to awaken to 5*

only increase the dmg on ice units or ice atks, so nasha for example can benefit for using it for her auto atks, while any red mage who can use blizzard could also.
