Player-versus-player gameplay is very important to World of Warcraft. However, the designers are mindful that players are very divided about this issue. Thus, Blizzard has made sure that there are two different server types at launch. On the normal servers, PvP combat is entirely consensual. You cannot be attacked by other players unless you want to be.

     The other server type is player-versus-player, and on this server, you can sometimes be attacked by players of the opposing faction without warning. On normal servers, you can enter into player-versus-player combat by storming enemy capitals, entering special PvP zones called battlegrounds, or by attacking the guards in enemy cities. In all cases, you have a choice to engage in PvP combat or not. .
