All I care about is Zeref, not the Spriggan 12, not Acnologia.

Personally, I view the Spriggan 12 as Zeref's loyalists, while Acnologia is a supplement to the story.

The problem with the arc is that they focus too much on the Spriggan 12 but not Zeref since he's the main villain of the series.

I said it before and I'll say it again, Zeref's intention is to wipe out all of mankind (according to his statement to Mavis and later Natsu). Getting Fairy Heart is just a supplement to his plans and the Spriggan 12 are just helping him further his goals.

Honestly, I'm just waiting for Zeref to get more focus.
