This in itself seems to be a problem they noticed and are now going to fix. From the OP:

Similar to Zodiac weapons, Anima weapons are based on the following concepts.
  • Will not be the strongest weapon at the same time as the rewards for clearing the hardest difficulty content.
  • Clearing the hardest difficulty content will not require you to obtain Zodiac/Anima weapons.
  • Creating these weapons will require you to put in effort over a longer period of time.
