Patch 1.6.0: Assault on Blackwing Lair was a major content patch for World of Warcraft. Among other changes, it featured the release of the Blackwing Lair raid instance, the introduction of the Darkmoon Faire to Azeroth, Battlemasters in major cities, and revamps of the Warlock and Warrior talent trees.

Blackwing Lair Released

Nefarian's sanctum, Blackwing Lair, can be found at the very height of Blackrock Spire. It is there in the dark recesses of the mountain's peak that Nefarian has begun to unfold the final stages of his plan to destroy Ragnaros once and for all and lead his army to undisputed supremacy over all the races of Azeroth. Blackwing Lair is a max-level, 40-player raid dungeon, with many new encounters and tempting rewards awaiting the intrepid adventurer that dares enter its halls.

Darkmoon Faire

A gathering of the exotic from around the world and beyond, Silas Darkmoon has brought together the Darkmoon Faire as a celebration of the wondrous and mysterious found in Azeroth. While the Faire spends most of their time in parts unknown, they do stop from time to time in Mulgore and Elwynn Forest. When the faire is on its way barkers will stop by Orgrimmar and Ironforge to announce its arrival.

Battlemasters

There is a new way to enter the battleground queues. Battlemasters! Located in each of the cities, right-clicking on a battlemaster will allow your character to enter a battleground queue just like you normally would if you touched that battleground's entrance portal. The functionality is exactly the same, so when it's your character's time to enter the chosen battleground, you will be teleported directly in. Local guards can give you directions on how to find the battlemaster that you're looking for.

PvE
Blackwing Lair introduced
Several spawns removed from Scholomance. This should make for a more enjoyable 5 player experience.
Phase shifted imps are no longer hit by Magmadar's Lava Bomb.

With an all-new set of reputation-based rewards, there's never been a better time to join the war!

General
The Stranglethorn Fishing Extravaganza is a grand new event set along the coasts of Stranglethorn Vale.

Patch 1.8.0: Dragons of Nightmare was released on October 10, 2005.

Disturbance at the Great Trees

Something is amiss in the Emerald Dream. Immense dragons with the shimmering emerald scales of the Green Dragonflight have been sighted guarding the portals at the Great Trees... but these once-noble creatures crawl with a new, strange menace, not the peace for which Ysera is known. Bring many allies should you dare to confront them; their powers are formidable and they will not hesitate to crush any who draw near.

The Stirring of the Silithid

The arid sands of Silithus are shifting. Something is awakening beyond the wall to the south... Aid the Druids of the Cenarion Circle as they delve into the mysteries of the desert. Seek answers behind the Twilight Hammer's presence. Discover more about the alien creatures known as the Silithid as you explore their hives. Many new endeavors await the high-level adventurer!

Hallow's End

Aid a sick orphan in a little trick-or-treating! Darkcaller Yanka, attending the Forsaken's Wickerman Festival, and Sergeant Hartman of Southshore are seeking your aid in keeping the enemy out of their holiday affairs -- are you up to the challenge?

As a direct result of this, many weapons have shifted position in their relative power. In particular, many Epic (purple) quality items are now more powerful than slower Superior (blue) weapons.

PvP
The percentage of players that may reach ranks 6 through 14 has been increased.

The Gates of Ahn'Qiraj

The Gates of Ahn'Qiraj will house two massive, unique dungeons -- the Ruins of Ahn'Qiraj, a 20-man raid dungeon, and the Temple of Ahn'Qiraj, a 40-man raid dungeon. As players delve deeper into the mysteries of Ahn'Qiraj, they will discover revelations of the Silithid infestation and their shadowy masters, the Qiraji. Players will have to complete a world event of massive proportions before they can open the Gates of Ahn'Qiraj on their realm.

Multiple Battlegrounds Queues

Players will be able to enter multiple battleground queues. No longer must you make the hard decision of which queue to join -- when queued for all three, you can join the first one available or hold out for that particular battleground which you've really got your heart set on. Should a queue open while you are already in a battleground, you may switch to the new battle or remain in the current on.

Patch 1.11.0: Shadow of the Necropolis was released on June 19, 2006.

Shadow of the Necropolis

Floating above the Plaguelands, the necropolis known as Naxxramas serves as the seat of one of the Lich King's most powerful officers, the dreaded lich Kel'Thuzad. Horrors of the past and new terrors yet to be unleashed are gathering inside the necropolis as the Lich King's servants prepare their assault. The Scourge marches again...

Naxxramas is the new 40-man raid dungeon that will present even the most experienced and powerful players with an epic challenge.

General
The cost to unlearn talents will now decay over time. This cost will be reduced by a rate of 5 gold per month to a minimum of 10 gold.
Logging back in after a disconnect from the server has been greatly improved, and players should now rarely receive the message
Temporary item buffs (e.g. poisons, sharpening stones and shaman weapon buffs) will persist through zoning or logging out.

PvE
Naxxramas, (40-player raid instance), a massive necropolis floating above Stratholme
Release timers have been be removed from instances. This includes dungeons, battlegrounds, and raid instances.
Instituted an anti-exploit measure on certain encounters (almost entirely raid bosses). These encounters will prevent people from zoning into the instance while that encounter is engaged. If you attempt to zone into the instance while that encounter is engaged, you will be resurrected at the outside entrance. We will be making adjustments to the entrances to Molten Core and Blackwing Lair to accommodate this change. Combat resurrections, soulstones, reincarnate, etc. will still work fine. This is primarily to combat graveyard rushing in instances.

PvP
An updated set of armor rewards have been added to vendors for Honor ranks 7, 8, and 10.
The armor rewards for Honor ranks 12 and 13 have been increased in level and stat point allocation.
New rank 14 weapons have been added! In order to give casters the same diversity of selection that melee currently enjoy we have added new caster items that are available to be purchased by Grand Marshals and High Warlords.

Patch 1.12.0: 戰鼓再響 was released on August 22, 2006.

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!

General
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.
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.

PvP
Honorable Kills now diminish at a rate 10% per kill rather than 25% per kill.
The deserter debuff will now continue to expire even while you are offline.
