User blog comment:FairyRaven/Fairy Tail Chapter 427: Pitched Underground Battle, Review and Commentary/@comment-25152698-20150406211400

I thought Bluenote was supposed to be foddered to display Natsu's progress as a mage, so it is a bit odd that Natsu defeated so many members of Avatar rather effortlessly, lol, which means we will more than likely get some more meaningful villains in this arc sometime in the near future.

Definitely looking forward to this clash between Gray and Natsu more than anything, as I want to settle the debate between devil slayer and dragon slayer magic once and for all. (Not that the battle itself will determine that, but rather hoping for an explanation during the course of the match)

Though, it does make me wonder: how did Gray manage to kill Frosch and apparently defeat Rogue with Gajeel nearby? Certainly makes me fearful as to how powerful Gray may be at this point, though in the past the three of them --Natsu, Gajeel and Gray-- were always meant to be at the same level.
