About the base game:

Guild Wars 2 features five different races and eight different professions, which themselves are divided into three different weight classes, you must choose from when creating your character. Unlike most other MMORPGs Guild Wars 2 doesn't feature the usual distinction between Tank, DPS and Healer. Instead every character is a jack of all trades with ten skill slots in total, five of which determined by their race, profession and equipment, one for healing and four of undefined roles that are unlocked through progression in the game, including an elite skill.
