I think one of Mira's Satan souls could probably beat the fairy armour. Maybe since they were rivals, Mira secretly has more Satan souls to be equal to each of erza's armors (like anything you can do I can do better ;) lol.) We need more Mira fights, and a nice epic one :D

As for natsu, I agree with him needing to learn dragon force on his own. Didn't Wendy already do this?
