When new content is added to the game, official system requirements may change. In version 1.12.0 the requirements for Windows were increased from requiring 256 MB to 512 MB of RAM. Official Windows 98 technical support was dropped, but the game continued to run there until version 2.2.3. Before Mists of Pandaria, World of Warcraft will officially drop support for Windows 2000.
World of Warcraft is set in the same universe as the Warcraft series of real-time strategy games and has a similar art direction. World of Warcraft contains elements from fantasy, steampunk, and science fiction: such as gryphons, dragons, and elves; steam-powered automata; zombies, werewolves, and other horror monsters; as well as time travel, spaceships, and alien worlds.
Seven expansions have been released: The Burning Crusade, released in January 2007; Wrath of the Lich King, released in November 2008; Cataclysm, released in December 2010; Mists of Pandaria, released in September 2012; Warlords of Draenor, released in November 2014; Legion, released in August 2016; and Battle for Azeroth, released in August 2018. Players are not required to purchase expansions in order to continue playing; however, new content and features such as higher level caps and new areas may not be available until they do so.
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.
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, and on October 15, 2013 the Cataclysm expansion was also applied. On October 15, 2014, Mists of Pandaria was applied to all accounts following the release of Warlords. 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. 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. As of the pre-patch release of Battle for Azeroth in July 2018, all expansions up to Legion are included in the base game.
World of Warcraft takes place in a 3D representation of the Warcraft universe that players can interact with through their characters. The game world initially consisted of the two continents in Azeroth: Kalimdor and the Eastern Kingdoms. Four separate expansions later added to the game's playable area the realms of Outland and Draenor and the continents of Northrend and Pandaria. As a player explores new locations, different routes and means of transportation become available. Players can access "flight masters" in newly discovered locations to fly to previously discovered locations in other parts of the world. Players can also use boats, zeppelins, or portals to move from one continent to another. Although the game world remains relatively similar from day to day, seasonal events reflecting real world events, such as Halloween, Christmas, Children's Week, Easter, and Midsummer have been represented in the game world. Locations also have variable weather including, among other things, rain, snow, and dust storms.
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
