I completely agree with Lidor. Though to be quite fair, if you want to chalk up Fairy Tail's victory to something that is legit confirmed in the story: Tenrou Island was still joined to the mainland, which should have conferred some of its protection to the shrunken landmass of Fiore. However, now that the deus ex has been separated, I wonder what excuses the author is going to offer up now when Gray enters Super Saiyan again and then actually manages to hurt Zeref.
