Han pasado cinco años desde los eventos narrados en Warcraft 3. La Alianza y la Nueva Horda viven en un estado de guerra fría, y mantienen una frágil y quebradiza paz, mientras reconstruyen sus reinos y tratan de recuperar su prosperidad. En Ventormenta, el rey Varian Wrynn ha desaparecido en circunstancias misteriosas mientras viajaba en misión diplomática a la isla de Theramore, por lo que en su ausencia, es nombrado rey su hijo Anduin Wrynn, todavía un niño, asumiendo la regencia lord Bolvar Fordragon y la misteriosa lady Katrana Prestor. En Orgrimmar, el jefe de guerra Thrall lucha por sacar adelante a la Nueva Horda.

World of Warcraft runs natively on both Macintosh and Windows platforms. Boxed copies of the game use a hybrid CD to install the game, eliminating the need for separate Mac and Windows retail products. The game allows all users to play together, regardless of their operating system. Although there is no official version for any other platform, support for World of Warcraft is present in Windows API implementations Wine and CrossOver allowing the game to be played under Linux and FreeBSD.[47] In addition, the Windows client allows for direct OpenGL rendering in Wine, making performance on Unix-like platforms comparable to the native performance seen on Windows.[48] While a native Linux client is neither released nor announced by Blizzard, in January 2011 IT journalist Michael Larabel indicated in a Phoronix article that an internal Linux client might exist but is not released due to the non-standardization of the Linux distro ecosystem.[49]

Blizzard routinely applies older expansions to all accounts as new expansions are released. On June 28, 2011, The Burning Crusade expansion was automatically applied to all previous Warcraft accounts at no cost. On September 19, 2012, the same thing was done with the Wrath of the Lich King expansion,[67] and on October 15, 2013 the Cataclysm expansion was also applied.[68] On October 15, 2014, Mists of Pandaria was applied to all accounts following the release of Warlords.[69] On May 17, 2016, Warlords of Draenor was applied to all accounts to coincide with the release of the Warcraft movie that gives a 30-day trial of the game.[70] All The Burning Crusade, Wrath of the Lich King, Cataclysm, Mists of Pandaria and Warlords of Draenor content is now effectively part of the original game, with all new World of Warcraft accounts automatically including these expansions upon creation.[67] As of the pre-patch release of Battle for Azeroth in July 2018, all expansions up to Legion are included in the base game.[71]
Tanques: tienen la misión de atraer los enemigos recibir el daño de estos, ya que tienen la capacidad de aguantar mucho daño y sobrevivir más que otras clases. Son personajes con muchos atributos defensivos (bloquear, esquivar, parar), muchos puntos de vida y armadura para reducir al máximo el daño que reciben. El juego usa un sistema para medir el foco de ataque de los enemigos llamado amenaza. Los tanques son los que más puntos de amenaza suelen obtener durante el combate y, por ende, reciben todo el daño, sin embargo, poseen una capacidad ofensiva muy reducida (es ahí donde se necesita el daño de los DPS). El tanque por excelencia suele ser el guerrero protección, pero con las expansiones, han ido mejorando las demás clases, como al druida guardián, al paladín protección, añadiendo a los caballeros de la muerte para diversificar este rol, los monjes maestros cerveceros y los cazadores de demonios venganza añadidos en la expansión Legion

The Warden's existence was acknowledged in March 2008, during the opening legal proceedings against MDY Industries.[125] The lawsuit was filed in federal court in Arizona, and also listed Michael Donnelly as a defendant. Donnelly was included in the suit as the creator of MMO Glider, software that can automatically play many tasks in the game. Blizzard claimed the software is an infringement of its copyright and software license agreement, stating that "Glider use severely harms the WoW gaming experience for other players by altering the balance of play, disrupting the social and immersive aspects of the game, and undermining the in-game economy." Donnelly claims to have sold 100,000 copies of the $25 software.[126]
