Mages aren't really different from experts, just that they focus on releasing energy, changing their nature to perform elemental attacks, such as breathing fire, and manipulating water and earth, among other abilities.
In fact, the wizard style only makes things more complex. They certainly have better control of their strength, since being able to change the nature of their attacks requires a lot of training, but also reduces their growth rate.
It is said that if a mage and an expert of the same level fight, there is a 90% chance that the mage will emerge victorious, but the higher the level, the more complex this difference becomes.
For example, in the case of the five supreme elders of the Wizard Union and Oliver. They are all super experts, but they are already old and are still weaker than Oliver, this is because they waste a lot of time perfecting their energy control to cast what they call magic.
