World of Warcraft Patch 5.4: Siege of Orgrimmar Patch Notes

This evening Blizzard released the official patch notes for Patch 5.4: Siege of Orgrimmar. They're pretty much what one would expect after months of testing ... long, detailed, and they contain all the juicy details that made it into the patch's final version.

Read on for the details about this massive patch; it's absolutely huge. As a reminder expect downtime tomorrow until at least 10am PDT -- and don't be surprised at all if it goes longer.

General

New Raid: Siege of Orgrimmar

The tensions stoked by Garrosh Hellscream's arrogance have reached a boiling point with the devastation unleashed upon the Vale of Eternal Blossoms. Now it's time for leaders of the Alliance and Horde to lay siege to Hellscream's capital and topple the ruthless Warchief once and for all!
Siege of Orgrimmar contains 14 new encounters across four expansive wings as members of the Horde and Alliance take the war directly to Garrosh's doorstep.
Learn more about the new encounters in Patch 5.4 Raid Preview: Siege of Orgrimmar.
Siege of Orgrimmar supports the following difficulty modes: Normal, Heroic, Raid Finder, and (new) Flexible Raid.
Information on the availability of each difficulty can be found in the Siege of Orgrimmar Raid Schedule.

New Feature: Flexible Raid Difficulty

This is a new raid difficulty designed for pre-made groups of 10 to 25 players or any number in between. This means it's possible to have raids of 15 or 22 players! Difficulty will adjust automatically based on the number of players present with encounters intended to provide a challenge roughly between Raid Finder and Normal difficulty.
Flexible Raid difficulty requires a pre-made group to join but has no minimum item level requirements or role restrictions. Both BattleTag™ and Real ID friends are eligible to participate.
Loot quality will be between Raid Finder and Normal difficulty and awarded through a personal loot system (similar to Raid Finder). Bonus rolls and loot specialization will also be supported.
Player spells with different target limits depending on raid size will gradually increase their limits based on the number of players in Flexible Raid difficulty.
Players will be able to earn raid achievements just like in Normal or Heroic difficulty.
Flexible Raid difficulty has a lockout that is separate from Raid Finder and Normal difficulty.

New Area: Timeless Isle

A mysterious island, lost for millennia to the currents of time, has emerged from the mists off the eastern coast of Jade Forest.
Players seeking to explore the Timeless Isle should visit their faction's shrine in the Vale of Eternal Blossoms.
The Timeless Isle is inhabited by all manner of strange and powerful creatures that will test the mettle of solo explorers, but great rewards await the brave and skillful: epic loot, bind-to-account gear, Mogu Runes of Fate, pets, mounts, fun toys, and much more.
The Isle is filled with secrets and mysteries, many of which dynamically become available to explorers. Keep an eye on your minimap while on the Isle for information on nearby events!
The Timeless Isle is home to five new world raid bosses! Players may face each of the four Celestials in a trial of combat.
Heroes who have earned the legendary cloak from Wrathion may access the sanctum of the fiery Yaungol demigod Ordos, atop the Timeless Isle.



New Feature: Proving Grounds

Proving Grounds is a new feature where level 90 players can test their mettle and undertake trials designed for Damage, Tank, or Healer roles to test and improve their combat skills in a safe, controlled environment.
To access the Proving Grounds, speak with an NPC in the Temple of the White Tiger in Kun-Lai Summit or a class trainer.
Each trial is available in four separate difficulties: Bronze, Silver, Gold, and Endless. Harder difficulties include more difficult and varied enemies.
Endless mode allows you to test your mettle against increasingly difficult enemies. Compare your best scores to friends and guildmates!
Learn more about this feature in our blog titled Proving Grounds Preview.

New Feature: Connected Realms

Connected Realm is a set of two or more standard realms that have been permanently and seamlessly "linked." Players on the same Connected Realm will be able to trade, send and receive mail, join the same guilds, access a single Auction House, run the same Raids and Dungeons, and join other adventurers to complete quests.
To make Connected Realm feel seamless, player's home realms won't be indicated in the game world. In certain places, such as chat, the players' home realms will be displayed next to their name.
Learn more about this feature in our Patch 5.4 Feature Preview: Connected Realms.

Redesigned Arena System

Players no longer need to create or join an Arena team to compete.
Similar to the Rated Battleground system, players in a party of the appropriate size (cross-realm groups are supported) may queue for an Arena bracket of the same size (2v2, 3v3, or 5v5).
Each player will have a personal rating that increase or decrease based on victories and defeats against other rated opponents. Opponents will be selected based on the average Match Making Rating of the party.
Conquest cap, requirements on gear and enchantments will be based on the player's personal rating.
The Arena ladder will no longer be sorted according to Battlegroup. Just like Rated Battlegrounds and normal Battlegrounds, all Arenas will now be region-wide!
At the end of an Arena season, the top players in a region will still earn titles and mounts.
For more details about the change to Arenas, please see the blog titled: Patch 5.4 Arena Update.

The Legendary Quest Continues

Wrathion's final quests are now available for dedicated heroes who have fought on his behalf throughout the pandaren campaign. He's waiting at the Tavern in the Mists in the Veiled Stair.
Complete Wrathion's final tasks on the Timeless Isle and upgrade your celestial cloak to Legendary quality!
Only players equipped with a Legendary cloak can reach the Sanctum of Ordos atop the Timeless Isle. (This privilege extends account-wide.)

Battlefield: Barrens

Vol'jin and his forces move beyond gathering supplies and into a full assault on the Horde capital. As such, the Battlefield: Barrens weekly quest will no longer be available once the invasion on Orgrimmar begins in 5.4.
Ravika, the Darkspear Rebellion Quartermaster, will no longer be available.
Latent Kor'kron armor tokens will no longer drop or be available for purchase. Players who still have a Radical Mojo will continue to be able to combine it with existing Latent Kor'kron armor tokens.

Vengeance gains from being critically hit have been reduced by 50%.
There are now diminishing returns on Vengeance gains while tanking multiple targets. Each additional target grants progressively less Vengeance.
So as not to affect Challenge Mode leader boards, the above Vengeance changes will not apply there. For Challenge Modes, Vengeance will continue to work as it did in patch 5.3.
Area knockback effects now all share a diminishing return category. After a player has been moved by one of these spells, the player will be immune for 10 seconds. This new category applies to: Fellash, Gorefiend's Grasp, Glyph of Explosive Trap, Thunderstorm, Typhoon, Ursol's Vortex, and Whiplash.
