For Lisanna's role, it can be seen another way: She allowed Mashima to give a believable reason for Mira to lose against Azuma, so that he could then be beaten by Erza. How else would she lose to Azuma?

I don't really remember, but isn't Cube above FT when the Guild explodes because Seilah maneuvers it there to show Kyôka her achievement? If Cube had not been there, it wouldn't matter if FT pinpointed its location for a brief moment, it would be just too difficult to get onto it. And it would be easy to lose it too as it can be controlled, contrary to Levy's assumption.

Despite Lisanna being portrayed as weak, I'm actually fond of her role as she actually allows Mashima to move the plot forward fluidly. ._./
