The eight BlizzCon is coming to your Convention Center this Friday, November 7 and Saturday, November 8, 2014. Prepare for two relentless days of Blizzard gaming and fellowship, including in-depth discussion panels with Blizzard developers, hands-on opportunities with the latest Blizzard games, and intense eSports tournaments featuring top pro gamers from across the earthly plane.

Patch 5.4.2 updated the old Raid Browser interface to work across all realms for Ordos, Celestials, and Siege of Orgrimmar Flex wings. This has made finding a group much quicker, allowing you to list your character or your own group in the Browser, as well as a comment.

Primary Stats
Armor pieces will always have some amount of Stamina and Armor value.
Armor pieces always have Strength, Intellect, or Agility as a primary stat. Plate has either Strength or Intellect. Mail and Leather have either Agility or Intellect. Cloth has Intellect.
In the cases of Plate, Mail, and Leather, the primary stat will change depending on your current spec. Specifically, casters (including healers) will get Intellect, and melee or tank specs will get Strength or Agility.
Secondary Stats
They won't change based on spec or armor piece.
Secondary stats on armor pieces can still include Haste, Crit, and/or Mastery.
Secondary stats on armor pieces will no longer include Hit, Expertise, Dodge, or Parry. These are being retired in Warlords, and will likely be removed even from existing gear.
Secondary stats on armor pieces will also no longer include Spirit, nor will they include Bonus Armor, which are reserved exclusively for non-armor pieces.
In addition, secondary stats on armor pieces may include several new stats we are exploring such as Readiness, Amplify, and Multi-strike.
Additional Properties
Finally, items may have tertiary stats. These include things like a bonus to Movement Speed, Sturdiness, Life Steal, Avoidance, and Cleave.
