The Cataclysm is here V2 !

Quote from Blizzard staff

* Casters will finally get a Legendary item in one of the first raids of the expansion.
* Cataclysm will change the ways abilities are learned. Abilities ranks are gone and ability will just scale progressively with levels instead.
* Most of the Talent Trees will be changed dramatically, a lot of the passive bonuses will be removed and talent trees should be more fun. (No more "Hurray! Level up! I just got 1% more hit!)
* There is no plan to allow players to train more than 2 profession.
* There is no plan to allow more than 2 specs with the dual-spec system.
* Bags might get slightly bigger with Cataclysm.
* You will never be able to cleanse the Corrupted Ashbringer.
* Developers want shaman to be good AE healers and might buff Chain Heal even more.
* Multi-passenger flying mounts could be added in the future. They might also allow crafters to craft 310% flying mounts if they already completed an achievement rewarding one.
* Every healer class can now dispell magic, the niches will other debuffs.
* Engineers might be able to craft bows in the future.
* If you already own a 310% mount, you might be able to boost the speed of all your 280% mount to 310% just to let you use the one that you prefer.


Hunter

* Hunter's new ammos might drop from bosses or bought with emblems, nothing is decided for the moment.


Priest

* Shadow Priests will most likely get a nuke without cooldown in Cataclysm.


Shaman

* Shamans (Elemental) looks like "turrets" in PvP for the moment, the idea is to make totems funnier in the future ("put a totem down and something cool happens") but not a lot of details for the moment.


Warrior

* Warriors won't be as affected as other classes by the itemization changes, the goal is to make other classes gears look a lot like what warriors have.


Archaeology
Archaeology is the new secondary profession that will be joining the ranks of cooking, fishing, and first aid in World of Warcraft: Cataclysm. Archaeology allows the player to unlock new abilities and rewards by discovering ancient treasures throughout the world. Each archaeologist uses the profession to uncover clues hidden in the world around them, such as troll relics or map fragments, and decipher their meaning, enabling the clever archaeologist to manipulate pieces of the past, learning the location of a treasure cache or valuable artifact. Such artifacts are highly sought after by the Archaeology Society, and they pay in gold and items for their return. Those who have mastered archaeology can find Titan artifacts, earning special currency used to unlock character paths and allowing the player to further customize their character.

Reforging

* Reforging is another way to customize your gear.
* It will be relatively cheap, you will need a Blacksmith / Leatherworker / Tailor / Jewelcrafter / Engineer to do it. Each profession get to reforge a type of items.
* It lets you reduce one stat for another. Some restrictions will apply, you can't put the extra stat on something that is already on the item.


Professions

* Multi-gains will be added, while you level up your trade skills, rare items will give you more points as you skill up. (Rare items will give you 5 points for example, while green bracers will only give one)
* Gathering should be a little more fun.
* Engineering is a very fun tradeskill, but it's either amazing or it sucks and everybody drops it. More convenient items like Jeeves or Wormhole Generator will be added to the profession in the future to get back to the roots of Engineering.
* Fishing will also have some big changes, no details yet but it's going to be more fun.


# MP5: This will be removed from items and replaced with Spirit. All healers will be given a meditation-like ability.
# Spell Power: Spell Power is being removed from items as well. Don't panic, we'll be improving Intellect so that it provides mana and Spell Power.
# Attack Power: We're removing Attack Power from items as well. Instead, we're allowing Agility to provide the necessary Attack Power for leather and mail wearers. Strength will provide the appropriate amount of Attack Power for plate wearers. This means leather and mail items will no longer be desirable for plate wearers.
# Defense: The Defense statistic is also being removed from items so that players no longer have to worry about juggling around "the cap." Tanks will receive the necessary anti-crit from talents, like Survival of the Fittest.
# Armor Penetration: This ability is too confusing and "mathy." It is being replaced with Mastery, a stat that makes you better at what you do. More on that later!
# Haste: Will also increase the rate at which you gain energy, runes, and focus. Retribution paladins and Enhancement shaman will have a talent that allows them to take advantage of this benefit.
# Block: Block Value is being removed. Blocking will now always mitigate a percentage of damage.
# Stamina: Players will notice more Stamina on gear as Defense, Spell Power, Attack Power and Armor Penetration are removed.

* The Path of the Titans will let players follow a path (not restricted to classes), this is a new talent system with new skills and passive abilities.
* A mastery system is being added as well, a lot of talents will be reworked to be more fun. The point is to get rid of a lot of the talent skills and not make you spend all your points in a talent tree just because it gives you more damage or higher crit chance.


Archeology

* Archeology is a new secondary profession, not many details about this one but we'll probably hear more about it in future panels.


Deathwing

* Deathwing, the leader of the Black Dragonflight will be the main vilain of the expansion.
* Deathwing heard the whispers of the Old Gods after the arrival of the Burning Legion, he eventually grew very powerful and also became very very crazy.
* His plan was to catch the Alliance and Horde unaware with something so massive that it would bring up the Elemental Planes.
* The Elemental Planes were created by titans to contain the elementals, they weren't happy with this decision and some of them like Ragnaros got really angry.


New races - Worgens

* Other races were discussed for the alliance, but the developers really felt that the alliance needed a monstrous race and horde needed something fun and tiny.
* Genn Greymane closed the Greymane Wall to block the Scourge's plague. Gilneas got nervous as the Scourge progressed to the south.
* Arugal was a patriot, he called the Worgens to battle for Gilneas but eventually was surprised by how dangerous what he called down was.
* Worgens are from somewhere else ... or even someWHEN else. They have a wolverine temperament and spent a lot of time trying to contain the beast within.
* Racial - Visciousness - +1% damage.
* Racial - Dark Flight - +70% run speed for 10 seconds.
* Racial - Abberation - Duration of Curses and Diseases reduced by 15%
* Racial - Flayer - Skinning skill increased by 15.


New Races - Goblins

* Goblins are a technological race from Kezan, their society is broken up into trade cartels run by trade princes. They are new factions and not the ones you can already see in game.
* The Cataclysm hit Kezan really hard and it's possibly destroyed. The goblins are now refugees on the Lost Isles.
* As a goblin you start as a neutral cartel and eventually join the horde as you progress through the questlines.

Old World

* We all left a little part of ourselves in Northrend and the old world will be much darker than it was to make heroism and brotherhood more meaningful like Warcraft should be.
* Every zones will be revamped with new quests, items, and art. The old world will be a brand new experience and you won't have to deal with the annoying agility/spirit quest rewards anymore.
* Azeroth is now flyable. Pretty much all the zones will be changed to some extent, some of them like Elwynn Forest won't change too much but others like The Barrens will be sundered in two by Deathwing.
* The Wailing Caverns are now a lush and verdant Area.
* Desolace now has a lot more waters and a lot of plants can be seen in the screenshots.
* The Horde finally conquered Southshore.
* Auberdine was destroyed and the night elves have set up a new camp north of it. Garrosh wants to expand the horde and has built a fortified camp at the south of the zone.
* Stonetalon has been cleaned by the Goblins, Azshara will be the new Goblin zone, and are using quarries in the mountains of Azshara to build their town.
* Apparently Orgrimmar will be rebuilt and reinforced with steel, it now looks a lot like Garrosh strongholds...
* Undercity has been redesigned to be flyable, it now looks much more impressive from the outside.


New Zones

* 7 new zones will be added : Twilight Highlands, Mount Hyjal, Deepholm, Uldum, Gilneas, The Lost Isles, Sunken City of Vash'jir.


Starting Areas

* The Worgens and Goblins starting zone level goes from 1 to 15.


Vasj'ir

* Sunken City of Vashj'ir will be an underwater zone and was the home city of Lady Vashj before the original sundering, this is a gateway to the Abyssal Maw. Going through the Abyssal Maw will take you to the Elemental Plane of Water, even if the zone will be underwater you will be walking on the sea floor here, new underwater mounts will be available and should have the same speed as normal flying mounts.


Deepholm

* Deepholm will be the new hub of the expansion, you will have portals here to let you teleport to Hyjal, Uldum, etc ... The Twilight's Hammer now serves Deathwing and have brought him back to full health in the Temple of Earth at the center of the map.
* Deepholm isn't really connected to Azeroth, the connection is where Deathwing emerged from the ground.


Uldum

* Uldum will have at least two dungeons and is heavily inspired from Egypt. The sea at the west of Tanaris was just an illusion created by the Titan and Uldum is actually a brand new zone. It is rumored to hold a super weapon. Uldum is also the home of the Tolvir, a race of stone-like cats created by the titans.


Plane of Fire

* Ragnaros used the cataclysm to come back from the Plane of Fire where we sent him and is now sieging the World Tree in Mount Hyjal to burn it down. Malfurion is back from the Emerald Dream. The whole zone (Hyjal) will make extensive use of phasing.


Twilight Highlands

* The Twilight Highlands will feature Grim Batol, Deathwing literally broke open Grim Batol as he emerged from the ground. This is the new Twilight's Hammer base in Azeroth and both Horde and Alliance will have a new port town with boats here. The Red Dragonflight is still here but has been pushed back to the west of the zone near the Wetlands.


Dungeons & Raids

* The Firelands will be a new raid dungeon, it will let you go to the Elemental Plane of fire and visit Sulfuron's Keep, Ragnaros will be here and he's really pissed.
* Uldum will feature two new dungeons, the Lost City of Tol'vir and the Halls of Origination (a titan city)
* Grim Batol will have a level-up dungeon and a raid instance.
* Skywall (Air Elemental Plane) will have a level-up dungeon and a raid instance.
* The Deadmines and Shadowfang Keep will be back in a brand new level 85 heroic version.
* Blackrock Caverns will be a new level-up dungeon located in Blackrock Spire. This is an entirely new dungeon, new art, new creatures, new everything.


Player vs. Player

* Battle of Gilneas will be a new battleground where the objective is to control the city by controlling as many districts as possible.
* Tol'barad will be a new PvP zone and will also be the most important daily quest hub. Just like Wintergrasp a battle will happen every few hours and the winning side will get access to the Tol'barad Prison and extra daily quests, the really profitable ones.
* Rated battlegrounds will be added to the game and should get you the same rewards as Arenas.
* New arena maps will be added.


This add-on is gettin` better and better by the minute !
