I love this theory. This means that, though 2nd and 3rd generation should normally be more powerful than 1st generation (Please, I'm not a hater, but I absolutely hated the Twin Dragons vs Natsu fight >.>), 1st generation DF should be equal to 3rd generation true DF and more powerful than 2nd generation DF. Some questions though. Can 2nd generation even activate true DF and, if not, does the lacrima in 3rd generation cause them to lose the ability to activate true DF?

On a sidenote, does anybody know what Sting eats. I mean, he was shown eating that arrow ...
