The main reason she became a knight was to hide the fact that she is the great saint reincarnated from the Demon King. But she has already used her power to produce mass healing. First was when helping the saintess apprentice at the lake, making is holy water which helped heal the beasts. The next is going to Sutherland and curing the Yellow Spot disease. I would love to see her doing more knightly duties, or training her swordsmanship instead of the author showing off how god-tier her powers are.
