World of Warcraft Client Patch 1.8.0 (2005-10-11)

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

When the decorations of Hallow's End light up Azeroth's cities, you know there's mischief afoot! Seek special vendors in Orgrimmar or Ironforge and get your hands on treats! Aid a sick orphan in a little trick-or-treating! Deathcaller 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?


General

Instant Attacks
The mechanics of most instant melee attacks have been modified to improve item balance. Previously, instant melee attacks did damage based on the damage range of the weapon, plus a bonus for the player's attack power. This bonus was then multiplied by the speed of the weapon. As a result, slow weapons did more damage than was intended, and fast weapons were considered inferior by most players. We have changed the way the attack power bonus is calculated for instant attacks. This change does NOT affect attack power calculations for normal melee attacks. Instead of multiplying by the speed of the weapon, the attack power bonus is now multiplied by a fixed number pulled from the following table:

Two-handed weapons: 3.3
Daggers: 1.7
All other one-handed weapons: 2.4
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.
This change was not made to reduce the power of instant attacks, but to correct the relative imbalance of weapon itemization. At a given level requirement, epic quality weapons should always be more powerful than superior quality weapons.
Please also note that all normal weapon swings will be completely unaffected by this change. The following abilities are affected by the design change: Sinister Strike, Ambush, Backstab, Whirlwind, Mortal Strike, and Overpower.

The cost per point of durability to repair plate, chain, and leather items has been reduced to be equal to the cost of repairing cloth items of the same quality.
You can now repurchase up to 12 items that you have sold to a vendor. There is now a buyback tab on all merchants that you can select to repurchase the last 12 items you sold since you last logged in. When your character leaves the game or zones to a different area, this list of items will be cleared, so if you have accidentally sold something, don’t wait to buy it back. Buy it back immediately.
Perception (Human Racial) is now usable while stealthed.
Guardians and pets in aggressive mode no longer attack civilians.
There is now a spell effect when you increase your reputation to a new level.
Channeled spells that are cancelled by movement can no longer be cast while moving.
Pets no longer break off attacks when their target is affected by Warlock Fear.
The "Knockout" mechanic has been renamed "Disorient" and all tooltips that referenced this mechanic should be updated.
PvP


Honor System

The percentage of players that may reach ranks 6 through 14 has been increased.
Lower-level players should advance in the Honor System more quickly than they had previously (although this change does not affect the highest ranks they can achieve).
Battlegrounds
Each Battleground has an individual turn-in quest associated with its related victory/loss condition. Upon completion of a Battleground, the winning side will be awarded three Marks of Honor while the losing side will be awarded one Mark of Honor. Three Marks of Honor may be turned in to the associated questgiver for Honor Points and faction increase. Should players complete this turn-in quest, they will find that the bonus Honor Points for completion are twice that of normal turn-in conditions (individual).
Players of levels 10 - 19 will now be able to participate in the battle for Warsong Gulch.
Alterac Valley has received an overhaul:
In order to keep teams in Alterac Valley more numerically balanced, players will now enter Alterac Valley on a one-for-one basis (i.e. if there are 30 players in the battleground for each side with 10 players in the Alliance queue and 2 players in the Horde queue, only two players from each team will be added, bringing the total to 32 per side).
The minimum number of players required to start a battle in Alterac Valley has been lowered to 20 (the maximum is still 40).
Points for completing the map and winning have been slightly decreased.
Graveyards and graveyard capture points are now at different locations. The banners players must interact with in order to capture a graveyard have been distanced from each other somewhat in order to alleviate "graveyard zerging" and make graveyards more meaningful to both defense and offense.
Several terrain changes were made to fix some geometry exploits as well as to adjust for the new graveyard mechanic.
Iceblood Graveyard has been fortified.
The Frostwolf Relief Hut now has appropriate guards.
A great avalanche has closed off both the eastern and western segments of Alterac Valley. This has displaced the Syndicate, the Wildpaw Gnolls, and many of the Winterax Trolls.
Due to the avalanche, Korrak the Bloodrager and a small band of surviving Trolls have made the Snowfall Graveyard their new home. Players will find that Snowfall is now under Korrak's control and they must defeat Korrak and his Troll guards if they wish to take Snowfall.
The quests Korrak the Bloodrager (Alliance), Korrak the Everliving (Alliance), The Legend of Korrak (Horde), and The Return of Korrak (Horde) have been removed from the game. The rewards for the initial quest involving Korrak have been moved and can be acquired by completing the quest associated with winning a match in Alterac Valley. We realize that some players may have had the Korrak quest and never completed it. These players may have already completed the quest for killing the General and thus might not be able to benefit from the rewards from the previous quest line. We have opted to add an extra quest step at the end of the General kill quests to reward players that fall under such conditions.
A new item has been added as one of the reward choices for the quests Hero of the Stormpike and Hero of the Frostwolf.
NPC difficulty has been scaled down. All NPCs have had their power reduced by 15-30%.
There is now a portcullis at the end of each of the entrance tunnels inside Alterac Valley. They will rise two minutes into the battle.
The PvP Tier2 Alliance and Horde Cloth armor sets have new updated textures.
Hunter traps no longer affect opposing players when the hunter is not flagged for PvP.

Nothing for Priests again, /cry.

Psychic Scream.. immune, resist, trinket /cry.

priest time will come, like useful high end talents!

watch out for inner focus devouring plague. thats gonna put on the hurt.

WEEEEEEE, we warriors get nerfs, but actually GOT SOMETHING IMPROVED!! Improved charge CAMERA ANGLE !!

lol niccce

The extra intercept out of frost nova will be nice, at least... but yeah, overall, most warriors got hit hard.

Somehow, that change actually benefitted me- my overpowers and whirlwinds will act at a speed of 2.4, as opposed to the 1.9 I have now. So amid all that, Thunderfury actually got buffed, slightly.

-Splug

yah but you all those +nature damage items you were rocking no longer effect the proc. so sad =\

I also heard talk on irc that Eye of shadow drop rate has been increased.

Please list other undocumented additions.


I tested the new AV with my Fury Warrior (laf, hes good though )
it's seems good now, Iceblood can't be easily capped now
Duration of AV battles have not changed

The NPC are easily soloable now and no longer a pest.

Obsidian Syndicate got 3 eyes of shadow in 5 hours of farming in Winterspring last night..

Who wants to help Vizden with his Eye of Shadow before he even has an Eye of Divinity?! wooh. JK ^_^

I'll help farm with my warrior if I have a fair shot of rolling for my priest. If the drop rate has truly increased this dramatically no reason we can't farm out a few for everyone that needs one. Except Quincy, he'll sell his for 5k in gold! Okay, that's a lie. 3.5k in gold!

I'll def come to farm one for me and more for others, and if we get lucky some for the guild bank for future newcomers.

so have trolls gotten better racial skills yet or do they still suck nuts?

lol... NS and ghost wolf. shaman starting to get some love =(

Dear God he's still alive!
