That's good to know! As for Serena, I don't disagree about his powers being kind of uninteresting, but still he is established as someone who is stronger than 4 of the strongest men in Fiore. That will make anyone defeating Acnologia look like an asspull, unless at least 5 people of Laxus or Gildarts level group together against him or something.
