World of Warcraft classes are divided into nine categories.
Players select one World of Warcraft class to represent their personalities and goals within the game world. Each race features a specific set of restrictions, thus each race will have a different profile of classes available to it.
Each class provides a unique profile of abilities and talents for the player to explore. Abilities represent skills and spells available to the class, and talents empower players to specify and define their role in the world. Within each class the player can explore three distinct talent trees.
