Magic can also be used as mostly a tool, like for day to day life, much like the show. Agreed to magic not being the main source of ability for combat, as there were already plenty of characters who were archers or other forms of combat. With magic, there should only be a few as to be more balanced. Another way we can handle magic could be such as that of Edolas in Fairy Tail where magic isn't in the people but rather weapons and other tools.
