Actually it's the opposite, Mira struggling against two fo soldiers make her look weaker. Erza struggled against 2 Spriggans, yeah she didn't beat one of them, and had some assistance in the other one, but it shows how bad the difference of strength Mashima wants to set between them.

Mira should've defeated the sword girls and struggle against Irene, that would make her look more on par as an S-Rank mage cause, out of the 4 current S-Rank mages, Mira is turning out to be the weakest, she doesn't seem to be on par with Natsu anymore too.
