As Nysha was alluding, your role depends on whatever skill or ability you're using at the time. Often, a person tanking in heavy armour and using some sort of pokey or smashy weapon will turn around and heal a companion when necessary. At that moment, the player who was a tank has become a healer, regardless of the fact that the person is holding a melee weapon and wearing heavy armour.
It can be a hard mold to break out of, considering the wealth of class-based games (computer-based and non-). With Ryzom, it is more "What do you want to do" (there are no limits) as opposed to "Who are you" (that's all you can do).
