Some significant nerfs to Holy paladins in this round of patches. Much angst on the forums.
Judgement of the Wise has been changed to grant you 33% of your base mana instead of 20% of your maximum mana.
As expected, JotW got changed to base mana to prevent healing paladins from using it.
Divine Plea changed to : You gain 25% of your total mana over 15 sec (Old - 10 sec), but the amount healed by your spells is reduced by 100%. (Old - 50%)
This spell is very odd. It's like being being given the ability to drink in combat. Except we can run around and hit things at the same time. I guess it might be good for off-tanking Prot paladins, or maybe Ret paladins during Hammer of Wrath, or maybe as an absolutely last-ditch gambit for Holy (though seriously, 15s of no heals equals a dead tank). I dunno, it just seems like Blizzard is scared of this breaking, so they make it unusable.
Infusion of the Light now reduces the cast time of your next Holy Light spell by 0.5/1sec. (Down from 1.25/2.5 sec)
Blah. Infusion of the Light was the one interesting talent in Holy. Now it's pretty much a Light's Grace clone, only with a trigger that is random.
The thing about IoL is that it was the one talent that changed how Holy played. Given that the current playstyle of Holy is extremely boring, a talent that mixed things up was very welcome. IoL gave a very strong incentive to weave Holy Shock into our healing rotation. It provided mobility, allowing you to heal on the run. You could do things like nurse a instant-HL while getting back mana with Seal of Wisdom, or heal someone else in the raid, confident that you can react quickly to a damage spike on your main target.
With the IoL change, Holy returns to being an immobile single-target-spam platform. Sometimes the spells have a short cast time, sometimes they have a long cast time, but it's still just spam.
Honestly, Holy now looks very unappetizing. It's quite possible that it is still powerful, but it is uninteresting. Pretty much every talent in the tree reduces cast time or increases crit. Very boring, and not very active.
Unconfirmed: Judgement of Wisdom now procs once every 4 seconds on the raid-level.
Previously, each individual would see a JoW proc every 4 seconds. Now it is being reported that one person will see a JoW proc at time 0, a different person at time 4, etc. This is a massive nerf to JoW.
On the plus side, Sacred Shield apparently scales at 0.75 damage prevented per SP per shield.
This looks like a pretty nice change for Sacred Shield, making it a very useful ability.
