Intent on settling in Durotar, Thrall's Horde expanded its ranks by inviting the undead Forsaken to join orcs, tauren, and trolls. Meanwhile, dwarves, gnomes, and the ancient night elves pledged their loyalties to the Alliance, guided by the human kingdom of Stormwind. After Stormwind's king, Varian Wrynn, mysteriously disappeared, Highlord Bolvar Fordragon served as Regent but his service was affected by the mind control of the black dragon Onyxia, who ruled in disguise as a human noblewoman. As heroes investigated Onyxia's manipulations, the ancient elemental lord Ragnaros resurfaced to endanger both the Horde and Alliance. The heroes of the Horde and Alliance defeated Onyxia and sent Ragnaros back to the Elemental Plane.
In May 2007, Blizzard filed a complaint against in Game Dollar LLC (trading as peons4hire) in U.S. federal court. In February 2008, the parties filed a consent decree in which in Game Dollar agreed to refrain from using any World of Warcraft chat or communication to advertise any business or sell any services relating to World of Warcraft.

Some of the challenges in World of Warcraft require players to group together to complete them. These usually take place in dungeons—also known as "instances"—that a group of characters can enter together. The term "instance" comes from each group or party having a separate copy, or instance, of the dungeon, complete with their own enemies to defeat and their own treasure or rewards. This allows a group to explore areas and complete quests without others interfering. Dungeons are spread over the game world and are designed for characters of varying progression. A typical dungeon will allow up to five characters to enter as part of a group. Some dungeons require more players to group together and form a "raid" of up to forty players to face some of the most difficult challenges. As well as dungeon-based raid challenges, several creatures exist in the normal game environment that are designed for raids to attack.
Questing was described as an integral part of the game, often being used to continue a storyline or lead the player through the game. The high number of quests in each location was popular, as well as the rewards for completing them. It was felt that the range of quests removed the need for a player to "grind", or carry out repetitive tasks, to advance their character. Quests also require players to explore every section of the game world, potentially causing problems for social gamers or roleplayers seeking somewhere quiet. Quests that required the player to collect items from the corpses of creatures they had killed were also unpopular; the low "drop rate", or chance of finding the items, makes them feel repetitive as a high number of creatures need to be killed to complete the quest. A large number of new players in a particular area meant that there were often no creatures to kill, or that players would have to wait and take turns to kill a particular creature to complete a quest. Some critics mentioned that the lack of quests that required players to group up made the game feel as if it were designed for solo play. Others complained that some dungeon or instanced group quests were not friendly to new players, and could take several hours to complete. Upon release, a small number of quests had software bugs that made them impossible to complete.

En Warcraft III la cantidad de razas y héroes creció más y las relaciones entre estos personajes se entretejieron de modo más complejo. A su vez, se establecieron algunas ideas sobre la cosmogonía y muchos elementos sobre la historia antigua para justificar una lucha ancestral de proporciones mayores entre los seres creados por las deidades metálicas llamadas titanes y los demonios liderados por el corrupto titan Sargeras. La lucha, sin embargo, no fue exclusiva entre la creación y los demonios, sino que entre las criaturas continuaron los odios raciales reforzados por las tradiciones bélicas. De este modo, la Alianza se mantuvo enemiga de la Horda hasta el final de la Tercera Gran Guerra con todo y que aparecieron nuevos peligros, como el Azote de los muertos vivientes, que comenzó como una simple plaga, o los territoriales elfos nocturnos. Al final, fueron cuatro las civilizaciones o razas las que se enfrentaron en la guerra: Los humanos, los orcos, los muertos vivientes y los elfos nocturnos, sólo después de haberse desgastado lucharon contra la invasión de los demonios liderados por Archimonde.
The practice of buying or selling gold in World of Warcraft has generated significant controversy. On February 21, 2008, Blizzard released a statement concerning the consequences of buying gold. Blizzard reported that an "alarmingly high" proportion of all gold bought originates from "hacked" accounts. The article also stated that customers who had paid for character leveling services had found their accounts compromised months later, with all items stripped and sold for virtual gold. The article noted that leveling service companies often used "disruptive hacks ... which can cause realm performance and stability issues". In April 2015, introduced a means to sell in-game gold for real money. A player may spend $20 on a one-month "game time token" that can be sold for in-game gold on the auction house.
