Mages think that the world is a struggling place for mages since the cells are introduced.
People use cell frequently rather than Magic because of Its easiness. They specialized in the magic against the cell. They are backing-up combat style mages. They are more skilled at defending themselves rather than giving damage to your enemy. They can weaken your enemy and make your creature stronger at same time.
It's impossible for mage to fight alone. But when they are working with other classes as a team, the situation will be reversed. They have healing magic and powerful long ranged magic attacks that is enough to support your team.
