DPS: sigla de daño por segundo. Se encargan de golpear al enemigo y bajarle la vida hasta derrotarlo. Son el tipo más diverso y hay de muchos tipos, a distancia (cazadores), cuerpo a cuerpo (guerrero, chamán mejora, caballero de la muerte, pícaro, paladín, druida feral, monjes viajero del viento, cazador de demonios devastación) y mágicos o los lanzadores o casters (mago, brujo, sacerdote sombras, chamán elemental, druida equilibrio). Sus puntos de vida suelen ser la mitad que la de los tanques, pero el daño que infligen es superior con respecto a los otros roles y prácticamente son estos los que acaban con los jefes en las bandas. Por esa misma razón, son el tipo de rol que se necesita en mayor cantidad en las bandas.
In December 2015, Blizzard sold an in-game battle pet named Brightpaw for $10 with all proceeds going to the Make-A-Wish Foundation.

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. 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. 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.
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.
