@Anon -> You can say that as many times as you want to but it ain't gonna change anything. Halphas vs. BSS was a fight that was planned by the Anime team. Anime Team =/= Hiro.

It has been implied and stated many times that Mirajane and Erza were somewhat equal before Lisanna disappeared. After Lisanna disappeared, Mirajane became a bartender and didn't train or went out on missions for 2.5 years (more if you take into account the time frame between Macao arc to Tenrou arc and GMG to Tartarus) while Erza continued to get stronger.

How would Mira be stronger than Erza exactly (evidence from Manga plz)?
