Optimizing your Holy Power Use

I got a question on my ToR build post about the change of LoD and the best use of Holy Power considering it. Just quoting a part of the question "I am getting mixed input with WoG vs LoD and which to use".

Light of Dawn has changed recently from being a fixed strength heal on a 30s CD to being cast with Holy Power and without CD. One important fact to keep in consideration is that is still activate Holy Beacon (though it is not sure this will continue).
This change has two important consequences.

First LoD is not as bad as before, with a 3 HP stack and reasonable spellpower it becomes a strong aoe (cone) heal, not far from 10K / target affected. The position issue remains, and it is still a bit situational, but if you can manage to get two or more people in your cone (plus you) it is now a strong healing output ability.

Secondly, Holy Power now has two uses, Word of Glory or Light of Dawn. Obviously the uses are very different, one is a single target strong heal that can benefit from 2 talents (Eternal Glory and Rule of Law), the other is a raid healing ability that only benefits from its own glyph.

From my point of view LoD has always been very situational, but this change makes it strong enough to be valuable in situations like infest heals in a Hard Mode Lich King fight, it wasn't strong/reliable enough before. I am still using an Eternal Glory / Crusade talent template at lvl80 for the reason that I find WoG invaluable when a quick strong heal is needed, which happens to be what I'm the most useful for at the moment (I raid with resto druids and damage spikes are the only thing they can't deal with much better than me).

But I wanted to get inputs for the future, so I went to look at some parsing for good raiding guilds in the last days of the beta (when this change was pushed and before beta was turned off). Here are the results.

There seem to be two "templates" for Holy Paladins now.

The first template is a tank healer based on the TOR build & rotation for mana efficiency and spike management. You will do a little bit or raid healing with Holy Shock and Word of Glory from time to time, but most of your heal will be on your tank. LoD will only used in very specific occasions, when the raid groups up or on the melee group nearby the tank, if you use it properly with Beacon it will also be a spike heal on your tank.

The second is based on LoD "spam" for raid healing, this will require you to move often to position as efficiently as you can, your Beacon should be on the tank at all times to use LoD Beacon proc. You will use a Divinity template as you'll nearly never use Word of Glory.
Both of these templates have been used in lvl 85 raids and are efficient enough for me to mention them, the first one seem to be the most efficient, close to the output of resto druids (which are still very strong despite the various nerfs they got lately). But I think this is due to the fact that a LoD build is harder to master and requires getting used to. You'll need to move a lot and depending on your position the number of persons you will affect with a LoD will strongly change your hps. Moving speed boot enchants are advised, and don't forget you'll main HP source will still be Holy Shock on a 6s cooldown, keep crusade for that.

We'll have to wait until raids are live for more inputs, but at least this give us a choice of spec and not only one direction and gameplay to focus on, which is always good.

Light of Dawn with more flashy flashy light ?

Two new builds hit the beta servers this week, I'm not going to detail everything but I want to notify you a change for one of the new spells we got with 4.0.1.
For detailed infos you can look at the build 13241 on MMO Champion.

Light of Dawn now uses Holy Power instead of Mana. Now heals up to 5 targets. No longer has a cooldown - Consumes all Holy Power to send a wave of healing energy before you, healing up to 5 of the most injured targets in your party or raid within a 30 yard frontal cone for 1008.96 to 1124.15 per charge of Holy Power.

What does that changes do? Both a buff and a nerf.
No more cooldown is a buff, even if dependent on Holy Power, getting 3 stacks of HP is usually much faster than waiting 30s.
It can now only heal 5 targets, whatever the positioning of your raid. This is clearly intended as a 25-Man raid healing nerf, you will never get more than 5 people in your "aoe cone" in a 10-Man. Blizzard is nerfing most aoe healing recently, especially the paladins which seemed to do too much of their raid healing via aoes (that's a change ...) no surprise LoD finally got the shaft too.

All in all I think that it's an interesting change, at least for 10-Man raiders which will not suffer from the nerf.
Now ... Light of Dawn is a crappy situational heal as it is right now on live. Will it be strong enough with a 3 Holy Power stack to justify its use is to be verified once these changes are live.

Up to now, most paladins are just playing with their "disco ball" and getting silly giggles on vent for using it, it's pimp, it's flashy, it's also near from useless in 10-Man where you will rarely heal even only 3 people with it (but for Festergut perhaps, if you're a lucky healer and sticking to the melee range, usually not the case of a paladin in hard mode).
We'll see what it will be.
