Here are a few highlights that I found interesting...
- Guild Finder = Guild Finder is a new system designed to enable easier and faster guild recruitment
- Dungeon Finder = The Dungeon Finder now attempts to avoid putting damage-dealing classes with the same armor type in a group.
- Zul'Aman and Zul'Gurub return as level 85 5-player heroics
- Arena = teams are now awarded guild experience for wins. The entire team must be members of the same guild to earn this experience.
- Professions = All major cities will now have every type of profession trainer and their associated trade supply vendors.
- And last but not least = CLASS CHANGES...
