Holy Paladin Mastery no longer activates periodic healing effects

Holy Paladin’s mastery has been hugely overpowered this expansion and has been one that has been constantly talked about because of the shields that mastery gives the raid.  However, Blizzard has made a change that should reduce the OPness of Holy Paladins slightly.

Mastery: Illuminated Healing no longer activates from periodic healing effects.

However, this remains to be seen just how much of an impact this will really have on Paladin’s healing.
