Player-versus-Player Combat

Player-versus-player gameplay is very important to World of Warcraft. However, not everyone wishes to engage in PvP combat. Thus, there are different realm types, normal and PvP, that will accomodate either preference. On 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, wow(eu) gold entering special PvP zones called battlegrounds, or by attacking the guards in enemy cities. You can also flag yourself for PvP by toggling the option in your player menu, wow account or attack an opposing faction player who is flagged for PvP (doing so will automatically turn your own flag on). In all cases, you have a choice to engage in PvP combat or not.
On PvP servers, there are many zones that are flagged as contested territory. In these zones, wow gold players from opposing factions can attack each other freely. Thus, you could be fighting monsters by yourself, only to be attacked by a stealthed enemy rogue. PvP servers also enable PvP combat through battlegrounds, attacking enemy guards, and entering enemy capitals.
The rewards for PvP play are excellent, sell wow gold however. Since the Horde-Alliance conflict is central to the Warcraft universe, player-vs-player combat is encouraged. As you defeat enemy players, you will accumulate honor points. You can then spend those points on honor rewards, maple story mesos such as special equipment, weapons, and mounts. Your honor points will never decay or decrease without spending them, so this system makes it possible to buy several smaller rewards or one large reward with the same number of points. Keep in mind though, that you will only gain points for defeating players near your level.
