@takashichea: I don't think Sting conceding when he should have won was the real PIS moment of the Arc, it was just disappointing for me. It was more so the fights that had PIS, Erza's most notably. Bending the laws of magic to her whim without even a penalty effect. Lesser versions of this are happening in every other Naruto chapter lately though. Kishi ignores the former logic that he himself established from the beginning.
