As he should be to some degree physical superior to her, as he warrior skills and leadership, and her purpose and role in the DC is not same as his. He is to be the Most powerful big gun, while hers is to be as the one who leads and guides , and is still really powerful in her own right!
So true! I don't know why people still complain about Superman's power level! He is supposed to be the most physically powerful hero in the DCU! No one complains about the Flash being too fast or Batman being too smart! Wonder Woman is powerful but she is known for her skill as a warrior.
