Cross-Realm Battlegrounds

For the first time in the history of World of Warcraft, you will be able to face off against players from other realms in the Battlegrounds. PvP Battlegrounds link Alterac Valley, Warsong Gulch, and Arathi Basin so that players from several realms will be combined into one huge matchmaking pool. Replenish your mana, sharpen your blades, and get ready for some brand-new challengers!

World PvP

The stage is set for intense, objective-based land battles as Horde and Alliance vie for control over important strategic positions and resources around Azeroth. Head out for Silithus and Eastern Plaguelands to engage the enemy on the field!



  • Threat Reduction Effects
    • This system has been redesigned to eliminate inconsistency in how the effects work. Previously, some were additive (for example: 30% reduction + 20% reduction = 50% reduction) while others were multiplicative (30% reduction and 20% reduction made 44% reduction, from 0.7*0.8). They are now all multiplicative. This also prevents unpredictable behavior when the total reduction percentage was equal to or greater than 100%. Please note that in almost all cases, when stacking multiple threat reduction effects you will experience less threat reduction than previously.
  • Haste and Slow effects
    • Previously Haste and Slow effects worked inconsistently, with spells working differently from weapons, and hastes and slows not acting as inverses of each other. We have revised the system so that all haste and slow effects work the same way, and haste and slow percentages of the same magnitude perfectly cancel each other out (30% haste and 30% slow combine to no change). As a result, we had to change the tooltip numbers on all spell haste effects, and on all melee and range slow effects. The numbers in the tooltips are different, but the game functionality is unchanged (other than slight rounding errors). Those tooltips that changed will now display larger numbers than they used to display. Conceptually, haste values indicate how much more of that activity you can perform in a given time. 30% melee haste means 30% more swings in a given time. Slow values indicate how much longer an activity takes to complete. 30% slow means an action takes 30% longer to finish.
  • The deserter debuff will now continue to expire even while you are offline.
  • Honorable Kills now diminish at a rate 10% per kill rather than 25% per kill.
  • Temporary item buffs (e.g. poisons, sharpening stones and shaman weapon buffs) will no longer persist through zoning or logging out due to technical issues. This feature is anticipated to be activated once more with the expansion.

cf. 1.12 Rogue Adjustments


  • Reincarnation should now display the cooldown timer when used.
  • Chain Heal - After the initial target is healed, the healing effect will jump to the most damaged target (by absolute health) within range. In addition, if a raid member is the initial target it will look for valid raid targets to jump to rather than non-raid targets as a priority, making it consistent with group targeted Chain Heals.

  • Shield Slam: This ability will sometimes no longer remove more than one beneficial effect from the target.

  • Earthshatter Set: The Lightning Shield bonus will now be removed if you lose the set bonus.
  • Eye of the Dead: Holy Shock now interacts properly with this item.
  • Ranged Elemental Damage: Our ranged combat system does not allow a ranged weapon to do a mix of Elemental (Fire, Frost, Arcane, etc.) and Physical damage. Many ranged weapons existed which were listed as doing Elemental damage and did not function properly (the damage was dealt, but was treated as Physical). All of those weapons have been changed to deliver the Elemental damage as a chance on hit effect. Hurricane was previously changed this way in 1.11. The following ranged weapons are also fixed in 1.12: Bow of Searing Arrows, Dwarven Hand Cannon, Heartseeking Crossbow, Dark Iron Rifle, Galgann's Fireblaster, Quillshooter, Shell Launcher Shotgun, Venomstrike, and Verdant Keeper's Aim.

  • Zandalarian Hero Charm: Item tooltip corrected to match the effect tooltip.
  • The Items that summon mounts have been changed in their color/quality. Items that summon normal mounts are now blue (superior)items and items that summon swift mounts are now purple (epic) items.
  • Fixed a bug that allowed you to use items which restored health or mana while you were already full health or mana.
  • Fixed a bug with the Jom Gabbar trinket which was causing it to trigger a category cooldown for a duration longer than intended.
  • Wrath of Cenarius: This item will now trigger from Arcane Missiles.
  • Clarified the tooltips for the Stormshroud armor and Kalimdor's Revenge to explain that they deal Nature damage.
  • Fixed a bug that caused the Blooddrenched Mask to hide a character's hair.

  • Engineering: Explosive sheep do fire damage instead of physical damage.
  • Goblin Land Mines and Compact Harvest Reapers will no longer lock out using other engineering devices until the land mine/reaper dies. Harvest Reaper was given a 10 min self cooldown to prevent too many reapers from being summoned at once.

Undocumented Changes (compared to the test realm patch notes)



  • In order to whisper a player from another server in your battleground you must append "-Servername" to the end of their name. These whispers will not show up on your screen, but will show up on theirs.
  • Conjured items are the only type of items that can be traded to players from another server (anything else will give an error message).
  • When you join a battleground, you are automatically added to a raid group. You MAY NOT leave that group. To speak in this raid, use /bg instead of /ra.
  • Leadership of the battleground raid is granted to whomever has the highest PvP rank when the raid is formed (approximately 1 minute before the battleground starts).
  • You may be in a battleground group and a regular group at once, but the battleground group will be the one you see in the party frame as well as the raid tab.
  • The mini-battlemap in will reopen automatically if closed. (This is likely a bug)

World PvP

  • Silithus and Eastern Plaguelands both now have battlemaps like battlegrounds do.

Honor System

Nethaera (Blizzard Poster)

  • The curve has been adjusted to allow more people into the ranks. No, I can't give specific details on how many where but it should help at least for now.


  • Ruthlessness still appears as a Improved Relentless Strikes pre-req but this is just a graphic bug.
  • Murder is now only increased damage to Humanoids but by 2/4% instead of 1/2%. (This is a bug [1])
  • Expose Armor is now a non-ranked ability and the armor reductions are by % ([2] -- Can someone test whether this still replaces sunder armor or if it now stacks?) -- TESTED: Expose Armor not stacking with and still replaces sunder armor.


  • Solenor the Slayer's Soul Flame buff can now be correctly removed.


  • Succubus and Voidwalker now speak when summoned.
  • The trick of Demonology specced Warlock Engineers using Jumper Cables to resurrect a pet that's been Demonic Sacrificed, thereby giving both buffs, has been removed. The buff from Demonic Sacrifice now vanishes whenever you have a pet active regardless of how that pet got (back) into the world.


  • The eating/drinking buffs are removed once you reach full hp or mana. This has the unfortunate side effect of making you unable to get the food buffs that require you to eat for 15 seconds if you are at full hp. This is probably somewhat bugged. (This is a bug [3])


  • The interface options dialog is now full-screen and opaque meaning it can no longer be used while moving.
  • Raid boss emotes are now shown in center of screen like a warning.
  • Target of Target can be set to show/hide depending on if you're in a group/raid or not.

IMPORTANT: Off-topic or entirely redundant posts are liable to get deleted. It is however in everyone's best interest to not post them in the first place - We'd rather slouken could spend his time coding us cool things than moderating this thread!


  • Added Color and BorderColor elements to the XML for backdrops.


  • There will be a new SendAddonMessage("prefix", "text", "PARTY|RAID|GUILD") method that transmits a 'hidden' message to the appropriate group of recipients as the normal SendChatMessage would have been.
