Yeah but it's her type of Magic that she uses. We have people like Natsu that train their bodies every day along with their magic. And then we have mages like Mirajane who can only fight if they change their physical capabilities, and she most likely only trains when she is using her Satan Soul, as training in her own body doesn't seem as though it would help.

That's why because of her Magic we have people like Erza who could spare with Satan Soul Mira while they just have a sword. And then we have Mira who would get crushed by the likes of Natsu if they both went at each other bare-handed.

Don't get me wrong I hold Mira in high regard( I see her as Erza level given what Mashima says), but if she is not using her Satan Soul I see her as fodder level( i.e one-shottable).
