The World of Warcraft servers will utilize an entirely new network architecture that has been designed from the ground up specifically for this style of gameplay. We created this next-generation architecture by incorporating our vast knowledge of multiplayer gaming along with our numerous Battle.net and Diablo experiences.
Players will be divided into several Realms, each realm comprising a complete version of the game world. The development team is currently finalizing the number of players that will occupy a Realm.
We are currently evaluating the optimal number of players per Realm. Our plan is to create a solution that fosters a sense of community and helps to prevent overcrowding. We understand fully that the number of players on a server directly impacts this and will be working closely with the community during the beta test program to fine tune this number.
Yes. In order to promote individuality, World of Warcraft will feature an advanced naming system allowing players to create a unique name for their characters on each Realm.
Most likely you will not be able to change Realms (servers) within the game without some type of request to Blizzard. Once a character is created on a server it stays on that server.
