I'm disappointed that Blizzard isn't providing Holy paladins with some kind of workable AoE damage tools. I can say from experience: the lack of AoE damage is severely hurting the leveling experience for Holy.
And this is a genuine problem, even for healers: there are solo encounters that are designed with AoE damage in mind. For instance, there's a quest in the Monastery in Jade Forest where you get zerged by countless monks with low maximum health, and the idea is that you kill them with AoE to avoid being overwhelmed. Also, there are swarms of insects around the Master's house that deal a stacking damage debuff on you, and the idea was again that you would AoE down those enemies as quickly as possible before it stacks too high and you die. But when you don't actually have any AoE damage tools that can AoE down these kinds of encounters, you're screwed.
Many paladins have complained about this, and there hasn't been a peep about it from Blizzard. However, Ghostcrawler himself said:
"OMG, GC didn't address the most important issue!"
I don't have the bandwidth to answer everything, but rest assured we read it all. If there is something particularly important to you for us to address, feel free to keep bringing it up (without just "bumps" please).
So---I'm bringing this up again here.
I've been aiming for Blizzard to correct this issue by giving Holy paladins either Consecration or Holy Wrath or both in patch 5.0.6/7---I've been figuring that Blizzard would release a small patch to correct any bugs that have come up since the launch of Mists, and that they could easily enough sneak in a change like adding an AoE damage spell to Holy's kit in that minor patch. And I've been trying to report every bug I see in-game, from permanently evading terracotta enemies in Kun-Lai Summit to the fact that Denounce has no positional requirement, hoping that a little extra bug-reporting would help speed in patch 5.0.6, and with it, relief for us Holy paladins.
But now that Blizzard is announcing the PTR for 5.1, it looks like patch 5.0.6 may not come. So I'm taking on a new aim, now: a hope that Blizzard will more thoroughly fix the issue of holy paladins having no AoE in patch 5.1. I'd like to add that I consider giving Holy back Consecration and/or Holy Wrath is something of a band-aid (though still workable as a permanent solution), but that it's also the kind of thing that can be sneaked in during patch 5.0.6.
An even better long-term permanent solution would be to make the behavior of the Denounce spell depend on which seal you have active: if Seal of Righteousness is active, then Denounce deals AoE damage---either as splash damage, or as a volley of holy bolts. (This would actually make Denounce close to what it was while Blizzard was going to have Holy Wrath be Holy's main nuke.) If Seal of Truth is active, then Denounce deals more single-target damage, either through Censure (which would need to scale with spell power) or through a straight-up percentage increase. If Seal of Insight is active, then Denounce costs no mana and has a chance to restore mana on hit. (I'd like to add that mana is actually an issue for me while I'm soloing as holy, and making Seal of Insight work this way would help a great deal.)
I think this Denounce+Seal solution is a better solution because it makes seals relevant for Holy, it gives Holy something it needs (AoE damage) without cluttering up our spellbars with more icons, it adds to the fun-factor by giving Holy paladins something to cast to restore mana in combat (giving us a heal-or-mana decision, much like how Telluric Currents and Power Word: Solace give shaman and priests a similar decision)---there's no downside to any of this!
...Except that it might get people's hopes up that giving Blizzard a good idea for their own class will actually make a difference for their own play experience in-game, of course ;)
