''For most fantasy MMOGs, the basic classes you can expect to be playing aren't too hard to predict. Whether you're a stalwart warrior with shield in hand, a crafty mage raining fiery bolts of destruction, a sneaky rogue with poison on his knife, or a benevolent cleric healing the wounds of his allies, you make up part of what's known as the holy trinity of MMOs: Tank-DPS-Healer. You need someone to get your foe's attention, someone to whack them over the head until they die, and someone to keep everyone alive until that happens. Everything else is just icing on the cake.''
