Here is a small list of changes relevant to Raiders and Dungeoneers that are expected to be implemented in the next content patch:

• Mobs inside Sethekk Halls will now continue to award Lower City reputation all the way into Exalted. Previously they stopped giving reputation in non-heroic mode just before players hit revered.
  
  
• The number of creatures that must be killed in the Karazhan Servants Quarters area before a miniboss spawns has been reduced.
  
  
• A new title available for level 70 players (i.e. not higher than that so you can't come back for it at 80) who complete the Tempest Keep attunement - Champion of the Naaru.
