I disagree. A fighter or group of fighters of 15th level or lower would still be hard-pressed to defeat a dragon without magic. Imagine - their armor and weapons are no longer magical, and the dragon's armor class is not even touched. The fighter group has lost anywhere from 5 to 10 points from their attack bonus (belt of giant strength, +5 sword, spells of true strike, etc.) and the dragon can bat them around like a cat's play toy. A dragon with about a 33 AC or so, and a +30 to its attack bonus is going to dine on freshly-peeled fighter without magic to help.
