Not at all. True heroes are way stronger than anybody else. Their flaws might be in that they lack civic skills themselves even while founding cities.
Come on, guys...I drag Tolkien and his creation Aragorn through the dirt, and nobody has anything to say about it? =]
There is a way to make a “perfect” hero interesting: Have his true feelings pop up unexpectedly. For example, Odysseus, when he approaches Nausicaa. He blesses her with finding a compatible husband, and when he expounds on the virtues of a man and woman of like mind, it becomes clear to the reader that he is longing for Penelope, a fact of which Nausicaa is ignorant.
Another interesting character is Menelaos, who says to Telemachus that if only Odysseus had made it home, he would have exiled the inhabitants of an entire town and moved Odysseus and his people there, just so they could spend time together. Gee, I wonder why Helen ran out on this bastard. But there, too, the facade has cracks and we see beneath to the real man, only this time it ain’t pretty.
