Guild Wars 2 has five playable races. They are:
Other than aesthetics and lore, the only difference between races will be
racial skills. Each race will have unique choices to make at character
creation which will provide a background story for that character. These
changes only affect the story the character experiences.
Along with the five races, there are eight Professions:
Different professions will have access to different weapons, skills
(excluding race-specific skills), and traits. Armor is dependent on
profession types; scholars (Elementalist, Mesmer, and Necromancer) will use
light armor, adventurers (Engineer, Ranger, and Thief) will use medium armor,
and soldiers (Guardian and Warrior) will use heavy armor.
Unlike traditional MMORPGs, there is no dedicated healer profession; instead,
any profession can perform any role, depending on their weapon skills.
Similarly, professions are not bound by race.
