Real question, even if he is, why would he care? Honestly allot of the criticism I hear for FT relates directly to style choices more often than execution. Like the dislike of friendship speeches, but everybody was energized when Goku told Loren not to mess with his friends. Another perfect example being the Zeref fight. Would I have preferred more flashy spells, hell yes. Yet the critique of the one-shot victory, lgnores that Zeref and Natsu were fighting in the background of at least 8 chapters. It downplays Natsu attempts to win beforehand, like when he erased him. It's a work of fiction, and open to critiques, but it was overall a good story, despite what minor things you or I might want to change.
