No matter how often you repeat that, to me making an object or person harder, stronger or faster is not the same as making the very air explode.

Sure both are manipulating the properties of the object, but in very different ways.

Besides if you reduce the magic to such simple terms, Brandish's magic is also enchantment (actually Brandish's magic is closer to Wendy's old buffing magic than throwing explosions...). As are parts of Juvia's Water and any kind of Make Magic since they allow manipulation of the element of choice along with the creation of said element.
