I completely agree that Minerva is being extremely underused here.

meh, I have no idea why people think Gray will be useful against E.N.D. Think about it, Acnologia is afraid of the guy (if Mard can be trusted on this), and FT, with 4 Dragon Slayers, their top mages (all healed by Wendy) could do nought against him. Looking at how damaged FT is at the moment and how Acnologia and Igneel are engrossed in their own titanic battle, there doesn't seem anybody out there who can defeat E.N.D. Not even all of FT + OS + CrimeS. My guess:
 * E.N.D. doesn't appear in this arc. He might never appear and just get destroyed while in his book form or get imprisoned.
 * Other Dragons come to take him down. Unlikey scenario: Igneel and Acnologia team up ...
 * The reason Igneel couldn't defeat him or Acnologia is afraid of him could be related to some aspect of him rather than his power, giving FT a chance to overcome him on their own. The only way Gray would be useful against him.
