Other useful info for 3.3:

• Divine Intervention: Cooldown on this ability has been reduced from 20 minutes to 10 minutes. Cannot be used in Arenas.
• Flash of Light: This spell no longer causes a heal-over-time effect unless the player has the Infusion of Light talent.
• Lay on Hands: This ability now places Forbearance on the target and cannot be used on a target with Forbearance.

Talents

• Holy
  -Infusion of Light: This talent now causes the paladin's Flash of Light spells to heal the target for 50/100% of the Flash of Light healing amount over 12 seconds.
  -Sanctified Light: This talent now also has a 33/66/100% chance to prevent Lay on Hands from causing Forbearance when Lay on Hands is used on others.
  
• Protection
  -Aura Mastery: This effect of this talent has been reduced in duration to 6 seconds.
  -Divine Guardian: This talent no longer increases the amount of damage transferred to the paladin from Divine Sacrifice. Instead it causes all raid and party members to take 10/20% reduced damage while Divine -Sacrifice is active. In addition, the duration has been changed to 6 seconds, however the effect does not terminate when Divine Sacrifice is removed before its full duration.
  -Divine Sacrifice: Redesigned. The effect of Divine Sacrifice is now party-only and the maximum damage which can be transferred is now limited to 40% of the paladin's health multiplied by the number of party members. In addition, the bug which allowed Divine Sacrifice to sometimes persist despite reaching its maximum damage has been fixed. Divine Sacrifice will now cancel as soon as its maximum damage value is exceeded in all cases. Finally, damage which reduces the paladin's health below 20% now cancels the effect early.
  
• Retribution
  -Repentance: This crowd control effect will no longer break early from the damage done by Righteous Vengeance.
