Hybrid class

Hybrid classes are classes which can fill more than one of the core PvE roles: tank, healer, or damage dealer (DPS). Realistically, no character can tank, heal, and dps at the same time, but hybrids are frequently flexible enough to serve in one role or another (no matter what spec they have) if they have collected the gear required to serve that function. ALL classes have at lease one method of fulfilling the DPS role, non-hybrid classes are sometime referred to as “Dedicated DPS” classes.

Definition of a hybrid
There are different views on how many possible functions are needed to consider a class a "hybrid". The most limited definition here would be any class that can fill any of the three roles. This definition would only consider Zone Masters and Gooptars as hybrids. Toshiko Games considers hybrids to be any class that has two or more functions that they can spec for. If the definition is widened in this manner, then Reapers, Werewolves, and Wizards are added to the list of hybrids.
