With the latest Beta build 8926, there are a lot of updates pertaining to the Paladin class. One I want to zone in is Reckoning.
Reckoning can now proc off a blocked attack. In TBC, reckoning can proc off hit and partial block (only). This is a minor buff that will assist in your AOE level grinding technique but still not enough to utilize in end-game content.
If Blizzard wants us to use reckoning, add holy damage.
