The official patch notes on the forums have been updated for an incoming PTR build. We've got the addition of arena points to high level battlegrounds as well as class changes for mages, death knights, paladins, shaman, and warlock.
Some of the major points coming out of this iteration of the patch notes include:
Meeting Stones: To use any Meeting Stone, it is only required that the character's minimum level be 15. There is no maximum character level requirement for any Meeting Stone.
All level 71-80 Battleground daily quests will now award 25 Arena points in addition to their current rewards.
Divine Intervention: Cooldown on this ability has been reduced from 20 minutes to 10 minutes. Cannot be used in Arenas.
Army of the Dead: The cooldown on this ability has been reduced from 20 minutes to 10 minutes. Army Ghoul damage dropped by 50%. Cannot be used in Arenas.
Lay on Hands: This ability now places Forbearance on the target and cannot be used on a target with Forbearance.
