Star Wars: The Old Republic, like many other MMOs, uses the Trinity System to define player roles in group combat. This means that players tend to fit into one of three roles when partied up: tank, damage dealer, and healer. For a quick explanation; a tank takes damage, a damage dealer deals damage, and a healer heals damage. These roles are obvious in a Player vs Environment situation; however, it is a lot harder to see where a tank fits in a Player vs Player situation. A tank’s role is more ambiguous in Warzones, where objectives and strategies are involved.
