Manual

Each race, in addition to its class selection, has unique racial traits. Some abilities
are innate, but not all abilities are available at the beginning of play. Some only
become learnable after you achieve a certain level, and others must be learned as
talents. In rare cases, a race might have to successfully complete a quest to unlock
a racial ability. Potential racial abilities can be seen at the Character Selection screen
when you click on the appropriate race.
There are nine available classes in World of Warcraft. Many share certain traits and
can be grouped into general categories. However, all have their unique strengths
and abilities.
