erste (unvollständige) patchnotes:
General
North American realms (excluding Brazilian, Latin American, and Oceanic realms) no longer permit letters with accents in character or guild names. Existing character and guild names with special characters will be unaffected by this change.
Transmogrification
This new feature allows players to customize their gear like never before. You'll find Transmogrification, Void Storage, and Reforging vendors in Cathedral Square, Stormwind and The Drag, Orgrimmar. The costs associated with this service are not yet final.
Void Storage
In addition to the bank, players will now have access to a new "deep storage" system, allowing characters to free bag space by setting aside coveted gear. You'll find Transmogrification, Void Storage, and Reforging vendors in Cathedral Square, Stormwind and The Drag, Orgrimmar. The costs associated with this service are not yet final.
Reforging
The former Reforging vendors have been... retired. The ethereals have chosen to take over the business and joined their Transmogrification and Void Storage service providers. You'll find them in Cathedral Square, Stormwind and The Drag, Orgrimmar.
Outland & Northrend Quest Flow
The amount of experience needed to gain levels 71 through 80 has been reduced by approximately 33%.
Many Group quests in Outland and Northrend have been re-tuned to allow players to complete them solo. They are no longer labeled as Group quests.
Relevant questgivers have been moved into Outland and Northrend dungeons. The majority of dungeon quests for these zones are now available from within their respective dungeons.
Achievements
The achievement Master of Alterac Valley no longer requires the Alterac Valley Blitz achievement.
Classes: General
Vengeance for Protection warriors, Protection paladins, Blood death knights, and Feral druids has been redesigned slightly. It no longer ramps up slowly at the beginning of a fight. Instead, the first melee attack taken by the tank generates Vengeance equal to 33% of the damage taken by that attack. In addition, as it updates periodically during the fight, it's always set to at least 33% of the damage taken by the tank in the last 2 seconds. It still climbs from that point at the rate it did previously, still decays when damage is not taken, and still cannot exceed a maximum based on the health and Stamina of the tank.
Threat generated by classes in active tanking modes has been increased to 500% damage done, up from 300%. This applies to druids in Bear Form, death knights in Blood Presence, warriors in Defensive Stance, and paladins with Righteous Fury active.
Death Knight (Forums / Talent Calculator / Skills/Talents)
Death Strike now heals the death knight whether or not the attack misses, or is dodged/parried. As a result of this change, Death Strike no longer refunds its rune cost if it fails to hit the target, as the death knight will still receive the healing effect.
Blood
Blade Barrier has been redesigned. It now passively reduces damage taken.
Bone Shield now has 6 charges, up from 4.
Veteran of the Third War now reduces the cooldown of Outbreak by 30 seconds.
Druid (Forums / Talent Calculator / Skills/Talents)

Hunter (Forums / Talent Calculator / Skills/Talents)
Coming soon.
Mage (Forums / Talent Calculator / Skills/Talents)

Paladin (Forums / Talent Calculator / Skills/Talents)
Holy Radiance now has a 3.0-second cast time, no cooldown, and requires a player target. That target is imbued with Holy Radiance, which heals them and all group members within 10 yards instantly, and continues to heal them by a smaller amount every 1 second for 3 seconds.
Seal of Insight, when Judged, no longer returns 15% base mana to the paladin. Judging Seal of Insight still causes damage, and melee attacks will still restore 4% of base mana.
Holy
Clarity of Purpose now also reduces the cast time of Holy Radiance.
Illuminated Healing (mastery) now also applies to Holy Radiance.
Infusion of Light now applies its cast time reduction from Holy Shock critical effects to Holy Radiance, in addition to its current effects.

Paragon of Virtue now lowers the cooldown of Divine Protection by 15/30 seconds, up from 10/20 seconds.

Glyphs

Atonement will now account for the target enemy's combat reach when calculating proper range, enabling it to be used on large creatures such as Ragnaros and Ala'kir.
Divine Aegis has a new spell effect.
Holy
Spirit of Redemption has been rebuilt to address a few functionality issues and make it more responsive. Spirit of Redemption otherwise remains unchanged.
State of Mind has been redesigned and is now called Heavenly Voice. Heavenly Voice increases the healing done by Divine Hymn by 50/100%, and reduces the cooldown of Divine Hymn by 2.5/5 minutes.
Glyphs
Glyph of Circle of Healing now also increases the mana cost of Circle of Healing by 20%.
Rogue (Forums / Talent Calculator / Skills/Talents)
Coming soon.

Reverberation now reduces the cooldown of Wind Shear by 10/20 seconds, up from 0.5/1 second.
Enhancement

Improved Lava Lash no longer increases base Lava Lash damage by 15/30%. This increase has been rolled into the base Lava Lash skill.
Mental Quickness has been redesigned. Instead of granting the shaman spell power, Mental Quickness now causes Enhancement shaman spells to behave as though the shaman has spell power equal to 55% of attack power. Enhancement shaman spells no longer benefit from spell power from other sources.
Restoration
Ancestral Healing now also causes the shaman's heals to increase the target's maximum health by 5/10% of the amount healed, up to a maximum of 10% of the target's maximum health, for 15 seconds. This effect does not stack if multiple Restoration shaman are present, and does not apply to heals from procs.
Riptide's periodic healing coefficient has been increased by 50%. The initial direct heal is unchanged.
