Why should not she be more powerful than natsu and gray?
Because she could be a hax? We've seen this before 'his/her magical power is insane etc.' but Natsu and Gray trained to be stronger, Natsu purpose is to defeat Acnologia, I think he can handle her, plus she's the weakest out of the 12, and Natsu still hasn't used Thunder Flame Mode or Dragon Force. Gray could probably use something like Demon Force or something too. Again yeah, they're surprised she's strong, but doesn't necessarily means she's stronger than them.
