I like how Crime Sorciere were put in the background despite it being their goal to defeat Zeref.

...Which brings me to what has been the most frustrating thing in this arc (and series). That is, Hiro giving characters a goal/purpose and not following through for no reason whatsoever.

1) What was the point of the 400 year plan? Why were dragon slayers brought from the past if they were going to be practically non-existent when it comes to the plan to defeat Acnologia? I won’t get my hopes up when Acno comes back because he’s immune to magic anyways(totally unnecessary), so its not like the DS can even do something. Is it too much to ask to give the other DS a little something, at least let them try.

2)What was the point of Crime Sorciere? First introduced over 270 chapters ago with set-up to face Zeref, their goal is re-established upon their arrival in Hargeon some 60 chapters ago and then what?....Not one single member of this guild even made eye contact with Zeref, or spoke a single word to him, nothing, absolutely nothing. Instead you let Natsu fight him 3 freaking times instead of giving these guys a shot. I’m not saying they should win, but at least make some attempt to have them follow through on their role in the story. Natsu can beat Zeref for all I care, just let these guys try and do something beforehand. Jeez.

Completely inexplicable how these characters with business in the Acno/Zeref fights got shafted. Inexplicable and extremely frustrating. Things that kept me interested in the story and now their chances of happening are practically zero.

Whatever. Looking forward to seeing if Hoteye and Wally will reunite and other epilogue stuff.
