General

• All players will have their talent points reimbursed and will have access to new talents throughout their trees; this includes the 41-point talents. Several new abilities have also been added for all classes.
• All pets will now receive a percentage of their master's armor, spell damage, spell resistances, attack power, and stamina.
• Low-level spells cast by high-level players will receive smaller bonuses from +healing and +spell damage.
• HoTs, DoTs, and channeled spells have been re-balanced to receive a more appropriate (higher) percentage of +spell damage and +healing.
• HoTs from different sources will now stack (i.e. multiple druids can cast the Rejuvenation spell on 1 target).
• New item property "Resilience" has been introduced. Resilience reduces your chance to be the victim of a critical strike, and reduces the amount of damage critical strikes do to you.
• Weapon Skill now does the following:
  • Weapon skill will no longer reduce the percentage damage lost due to glancing.
  • The player will gain 0.1% to their critical strike rating per weapon skill against monsters above their level.
• When casting a buff on a low level target, the appropriate rank of the buff will automatically be applied.
• In PvP, Crowd Control effects will last no longer than 12 seconds instead of the full duration, with a chance of a heartbeat resist.
• Players will no longer lose faction when under the influence of "Mind Control" or the Gnomish Mind Control Cap.
• Several improvements have been made to the Macintosh client, including support for Multi-Threaded OpenGL on Intel Macs running OS X 10.4.8 or higher.

PvP

  • Current honor totals have been reset.

  • Honor points earned each day may now be spent as a form of currency.
  • Check the PvP tab of your character sheet to see your honor information.
  • PvP rewards are no longer unique.
• Marks of Honor earned from battlegrounds are no longer turned in for reputation or honor. They are now used in addition to honor points in order to purchase rewards.
• Two New Arenas are now available in three different modes.
  • 2v2, 3v3, and 5v5 matches
  • Players may queue up at Goblin NPC's in Stormwind, Ironforge,
  • Orgrimmar, Undercity, and Gadgetzan

Druids

• The talent "Swiftmend" will now include bonus healing from the talents "Improved Rejuvenation" and "Empowered Rejuvenation".
• "Omen of Clarity's" duration has been increased to 30 min.

Hunters

• Traps can be set while in combat, but require a 2 second arming time.
• "Auto shot" will be automatically enabled if the Hunter steps out of melee range while in combat with target.
• 1 Agility will now grant 1 Ranged Attack Power.
• "Auto shot" is now reset when casting Aimed Shot.
• "The Beast Within's" Bonus damage caused has been reduced to 10%, but now also reduces the mana cost of all spells by 20%.
• Freezing Traps will now cancel combat when cast.

Mages

• "Frost Nova" (Water Elemental Spell) has now been renamed "Freeze".

Shaman

• Shaman with the appropriate talent spec are now able to dual-wield.
  • Self-weapon buffs such as Windfury Weapon can be applied to both main and off-hand weapons.
• Rockbiter's weapon functionality has been changed. It is now a damage proc instead of a flat attack power bonus.
• Windfury Weapon and Rockbiter Weapon enchantments will only benefit the weapon with the enchantment on it.

Warlocks

Warriors

• Rage generation from dealing damage has been normalized.
  • All Rage awards are averaged with our expected rage per swing (adjusted for weapon speed).

Items

• The "Far Sight" effect has changed so that the camera now zooms in to a distant location, rather than instantly showing the distant view. This also affects the items: Ultra-Spectropic Vision Goggles, the Ornate Spyglass, and the Hunter ability "Eagle Eye."
• Spells can now require either a totem item or a totem category item to cast a spell. This means that the Enchanting Rods now count as all of the lower level enchanting rods as well, so you only need a single enchanting rod instead of all six. This also means that "Finkle's Skinner" now counts as a Skinning Knife. Several weapons that are picks have been flagged as counting as a Mining pick as well.
• Items that give bonuses, such as critical strike percentage, have been modified to adhere to a combat rating system.
• All current items will provide the exact same benefit from ratings at level 60 as they provided before the ratings system.
• Thrown weapon items no longer stack, but use durability instead. One unit of durability is lost per throw, and these items can be repaired.

• The "Skull of Impending Doom" has been changed and will now increase run speed by 60% for 10 seconds, but deals damage equal to 60% of your maximum health and drains 60% of your maximum mana for over 10 seconds.
• The Backfire effect on the "Net-O-Matic" will no longer break on damage.
