I disagree with that.
The fact that ordinary armies are no match for a powerful Magical character does not mean that said character would lack all types of challenge, enemies and threats to worry about.
A good example of a threat for powerful Wizards or Mages would be others of their kind, just to start with. They could find themselves in a fight, or perhaps they would be threatened by supernatural monsters of great power. We can always come up with challenges adequate for the characters in question, it just needs to be adapted to their capabilities.
The Lightyans (Mages) in my Joan of England trilogy are not among my most powerful characters, but they are still capable of wiping out entire cities or even annihilate their planet if they wanted to...
Still, Joan and her friends have loads of trouble to worry about.
