In September 2006, reports emerged of spoof World of Warcraft game advice websites that contained malware. Vulnerable computers would be infected through their web browsers, downloading a program that would then relay back account information. Blizzard's account support teams experienced high demand during this episode, stating that many users had been affected. Claims were also made that telephone support was closed for isolated periods due to the volume of calls and resulting queues.[115] In April 2007, attacks evolved to take advantage of further exploits involving animated cursors, with multiple websites being used.[116][117] Security researcher group Symantec released a report stating that a compromised World of Warcraft account was worth US$10 on the black market, compared to US$6 to US$12 for a compromised computer (correct as of March 2007).[118] In February 2008, phishing emails were distributed requesting that users validate their account information using a fake version of the World of Warcraft account management pages.[119] In June 2008, Blizzard announced the Blizzard Authenticator, available as a hardware security token or mobile application[120] that provides two-factor security. The token generates a one-time password based code that the player supplies when logging on. The password, used in addition to the user's own password, is only valid for a couple of minutes, thus providing extra security against keylogging malware.[121]

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]
World of Warcraft was the world's most popular MMORPG by player count of nearly 10 million in 2009.[5][6] The game had a total of over a hundred million registered accounts by 2014.[7] By 2017, the game had grossed over $9.23 billion in revenue, making it one of the highest-grossing video game franchises of all time. At BlizzCon 2017, a vanilla version of the game titled World of Warcraft Classic was announced, which planned to provide a way to experience the base game before any of its expansions launched. It went live at 3pm PDT[b] on August 26, 2019.[8][9]

In China, because a large number of players do not own the computer on which they play games (e.g. if they play in Internet cafés), the CD keys required to create an account can be purchased independently of the software package. To play the game, players must also purchase prepaid game cards that can be played for 66 hours and 40 minutes.[55] A monthly fee model is not available to players of this region. The Chinese government and NetEase, the licensee for World of Warcraft in China, have imposed a modification on Chinese versions of the game which places flesh on bare-boned skeletons and transforms dead character corpses into tidy graves. These changes were imposed by the Chinese government in an attempt to "promote a healthy and harmonious online game environment" in World of Warcraft.[56][57] The Chinese government delayed the release of the Wrath of the Lich King expansion, due to what it deemed objectionable content.[58] NetEase took over licensing of World of Warcraft from The9 in June 2009 following the expiration of The9's contract,[59] and were able to secure a launch for Wrath of the Lich King on August 31, 2010, nearly two years after its Western release.
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.

World of Warcraft won several awards from critics upon release, including Editor's Choice awards.[10][20] In addition, it won several annual awards from the media, being described as the best game in the role-playing and MMORPG genres.[87] The graphics and audio were also praised in the annual awards, with the cartoonish style[88] and overall sound makeup being noted.[89] The game was also awarded Best Mac OS X Entertainment Product at the 2005 Apple Design Awards.[90] Computer Games Magazine named World of Warcraft the best computer game of 2004, and the magazine's Steve Bauman described his "feeling that Blizzard has analyzed every element of every existing game, pulled out the best ones, and then lovingly lavished an absurd amount of attention to their implementation." It also won the magazine's "Best Art Direction", "Best Original Music" and "Best Interface" awards.[91]
