Roles in a Group or Raid


 * Main Tank:(aka MT) The player, in a group or raid, expected to keep and control agro. Usually a wearer of Plate Armor, he should be able to handle the damage while the other players kill the mob. The Main Tank is not expected to deal high DPS.
 * Secondary Tank:(aka ST) The player designated to take over as Main Tank if the MT dies.
 * Main Healer:(aka MH) The healer expected to do most of the healing for the MT. the MH's ONLY job is to keep the MT alive. Sometimes, in raids, all healers in the MT's group are considered MH but may divide some of the work. For instance, with 3 healers one may have primary responsibility for all Cures, while another takes care of debuffs on the target, leaving the third healer free to concern himself only with the MT's health.
 * Secondary Healer:(aka SH) All other healers in the group or raid. An ST's job is to heal any of his group members that become harmed, while keeping an eye on the MT and assisting if needed. Also, ST's are usually the designated Ressurecters (rezzers).
 * DPS:(initialism for Damage Per Second) Scouts and Mages, primarily, are responsible for taking the target down without drawing agro away from the MT.
