I agree with @IamJakuhoRaikoben. Natsu himself said during the GMG that Mira was "as powerful as she used to be", and Mira used to be a match to Erza Scarlet herself - who have been stated as stronger than Natsu SEVERAL times before the 1year timeskip. Natsu has gotten stronger now, okay, but I'm pretty sure that Erza and Mira are hell more powerful too, keeping the Tiers valid. Learn something: Natsu only wins his battles because he's the main character :D It's not like he has a Nakagami Armor that breaks (or controls) the Laws of Magic and he isn't either a Demon.
