How do you fight people in World of Warcraft?

Answer 1

There is ten different classes/heroes, each is designed in its own way. You fight NPC's (non-player character, a computer) by using spells and hitting with a melee/ranged weapon.

There is spellcasters and melee, they differ a lot. Melee has a higher amount of defense meanwhile the casters has less defense. If you would like to read more about the heros/classes of World of Warcraft, check out the WoWWiki site.
