===Aggro===
One important concept to understanding the Tank is "Aggro": Monsters target whoever has done the most damage or healing nearby, but Tanks have abilities that either force monsters to attack them, or greatly increase their own Aggro rate without necessarily doing any damage or healing. 

Aggro management is quite important in most MMOs, as most Healer and Damage classes are fairly fragile, and an Aggro system gives players a fairly direct and decent risk/reward system, realism be damned. 

(See also the [[DISTRACTION CARNIFEX]], which is a case of Real World Aggro management.)
