Su utilidad radica en su capacidad de ser Heal o DPS, dependiendo de la rama de talentos que tome el jugador, aunque preferentemente está diseñado para la sanación. Usan la armadura de tela, por lo que no son buenos en el combate cuerpo a cuerpo. Emplean el conocido sistema de maná para usar sus facultades, este disminuye a medida que las utilizan, pero se regenera periódicamente y a diferencia de la Ira, solo está limitada por el equipamiento del personaje. Posee dos ramas de talentos dedicadas a la curación, una de ellas es más rápida pensada para curar individualmente y en el uso de escudos, además de tener que hacer daño para aumentar la sanación (Disciplina), y la otra para curar a grandes cantidades de manera colectiva, aunque tarde más en cargar las habilidades (Sagrado), o bien pueden desempeñar el rol de DPS usando la rama de talentos especializada en el uso magia oscura de daño periódico (Sombra).
The soundtrack for World of Warcraft was composed and arranged by Jason Hayes, Tracy W. Bush, Derek Duke, and Glenn Stafford and conducted by Eímear Noone. It was released on November 23, 2004, together with the collector's edition of the game. It is sold separately on one CD in the MP3 format. On January 12, 2011, Alfred Publishing produced an officially licensed sheet music series for vocalists, pianists, strings, and other instruments, World of Warcraft Sheet Music Anthology in solo and accompaniment formats with CD. These works include four pages of collectible artwork and vary by number of songs included. In 2018, a remix of the song from the game, "Hymn of the Firstborn Son", was nominated for "Best Game Music Cover/Remix" at the 16th Annual Game Audio Network Guild Awards.
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.
World of Warcraft received very positive reviews upon release, following a period of high anticipation before launch. Although the game follows a similar model to—and was noted for using many familiar concepts from—the role-playing genre, the new approaches to reducing pauses between game encounters were well liked. A common example was the approach to character death. In some previous MMORPGs, a player would suffer a high penalty for character death; in World of Warcraft, a player is able to recover and start playing quickly. Combat was another area where "downtime", or pauses between play, was reduced. By allowing all character types to recover from damage taken, players can return to combat quickly. Reviewers felt that these changes in pacing would make the genre more accessible to casual players—those who play for short periods of time— while still having "deep" gameplay that would attract players of all levels of interest. The concept of a "rested bonus", or increasing the rate at which a player's character gains experience, was also welcomed as a way for players to quickly catch up with their friends in progression.
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. In June 2007, World of Warcraft player Antonio Hernandez filed a class action lawsuit against IGE for interfering with the intended use of the game.
