I believe that you are giving Wendy and Sherria too much credit there, Queen. Despite the power they've displayed, the Sky Sisters are only teenagers—being 13 and 16 respectively. Compared to the majority of other characters within Fairy Tail, these two have not even hit the peak of their magic maturity and aren't really combat-orienated, especially in Wendy's case. While it might seem typical in a Shonen manga, it is quite honestly the only way that Wendy and Sherria are going stand an actual chance against DIOmaria and keep Carla from the great cat in the sky.

Plus, we get to see exactly how strong they potentially could be if they had the time to properly train.
