Not only do gamers who play World of Warcraft have the opportunity to give feedback and comments to game designers on the game's forums, but there are also ways to play the game's future patches by getting on the test realm to experience content that is still under development. Generally a player must have an active account so if a person decides to sell WOW account then he'll have to obtain another account in order to experience the test realms. It's not difficult to get a new account but doing so might not be a good idea because all the characters would be new instead of max level.
