Judging light and parse envy...

The Story
Recently another Holy Paladin joined the ranks of my regular 25 man raid team. We have a good team of healers. The parses show load is balanced with everyone doing basically the same effective healing. There's only so much effective healing and if everyone is doing their job a natural balance will occur.

Looking at some parses of  failed  Blood Queen attempts (missed bites!) and the new Big Healer was doing a good 2K more HPS on each attempt. A little analysis shows the difference was Judgement of Light. He managed to keep his Judgement active.

The Mana

Every time Judgement of Light is cast with the Seal of Wisdom active you gain mana. As long as no one needs a heal, then Judgement should be used when it's on CD.

Again, Judgement should be cast when it's on CD when no one needs a heal.

The Timing

A 10 second cool down (not improved) allows 6 judgments a minute.  If you are the only Paladin casting Judgement of Light, it will take 4 casts per minute to maintain the debuff.  The talent Judgement of the Pure provides a 15% haste bonus and requires the Big Healer to judge at least once a minute.

The Wisdom or Life Decision
The Judgement of Light provides health to the Raid, the Judgement of Wisdom provides mana.  Providing more mana to the raid increases the raid's DPS.

The Who
Relatively recent changes to the way the Judgment debuffs work means it doesn't matter which spec of Paladin is doing the Judging.  The Retribution paladin should be Judging as part of their DPS rotation and will have no problem maintaining the debuff.  Assign them the wisdom debuff and the mana deeps will be happy.

The Conclusion
This Big Healer has started to be more aggressive on Judgments and as a result the balance has been restored to the parses.
