The various news sites have a first look at Tier 12 set bonuses. (MMO-Champion, Wowhead)

Holy Paladin:

Paladin T12 Holy 2P Bonus: Casting Flash of Light, Holy Light, or Divine Light on your Beacon of Light target has a 40% chance to grant you 2% of your base mana.

Paladin T12 Holy 4P Bonus: Your Divine Light also heals a nearby injured target for 20% of the amount healed.

Obviously, we don’t know how these bonuses will work, yet, but there are a few things here that are interesting to note. Typically, Blizzard ties bonuses to spells they want us to use a lot. Witness our 2pc bonus (and any other healer’s T11 2pc bonus): it’s 5% crit on Holy Light/Heal/Healing Wave/periodic Lifebloom heals. (Never mind the fact that a lot of people go for offset pieces due to the lack of haste on tier, at least for paladins.)

Let’s talk about the 2pc bonus first.

a) You need to be casting Flash of Light or Holy Light or Divine Light. This effect does not trigger from Holy Shock, Word of Glory, Light of Dawn, Holy Radiance or, it appears, triggers from Beacon of Light.

b) You need to be casting those spells ON your Beacon target. This is in line with the Tower of Radiance talent that some paladins forego entirely and is, perhaps, Blizzard’s way of trying to encourage us to cast on our Beacon directly.

c) There’s a 40% chance to get back 2% of base mana. Do you know how much, or, rather, how little mana 2% is? Try 468 mana. So we have to cast a heal that’s about 7k (FoL) or 2k (HL) or nearly 8k mana (DL) in order to have a CHANCE to get 468 mana back. Not sure about you, but unless this changes, I’m just going to heal as I normally do and consider that mana to be icing on the cake.

It’s particularly insulting to us, given what the other healing classes are potentially getting. (And yes, I know, it’s datamined PTR info that’s subject to change.)

- Druids: Your periodic healing from Lifebloom has a 40% chance to restore 1% of your base mana each time it heals a target.

That’s a 40% chance to gain 186 mana each time Lifebloom TICKS. Lifebloom ticks (unhasted) once a second. Good resto druids, as I understand it, should ALWAYS have Lifebloom ticking on someone for Omen of Clarity procs, due to Malfurion’s Gift. In our first-ever heroic Chimaeron kill, my resto druid had 423 ticks or tick/crits of Lifebloom.  40% of that is 169. So, roughly, 169 chances to proc the bonus, assuming no internal cooldown.

- Priests: Your Flash Heal, Heal, and Greater Heal spells cause you to regenerate 2% of your base mana every 5 sec for 15 sec.

That is a 100% chance (no percent chance, no chance of failure) to regen 412 mana every 5 seconds for 15 seconds. So that’s 412 times 3 for a total of 1236 mana every time they use Flash Heal, Heal or Greater Heal.

- Shaman: Your periodic healing from Riptide has a 40% chance to restore 1% of your base mana each time it heals a target.

That’s a 40% chance to restore 234 mana on each Riptide tick. And you can have more than one Riptide going at once.

Clearly, the holy paladins have been screwed over here. The shaman and druids have the same chance as us to proc, but are restricted to one spell. However, that one spell (for both of them) ticks constantly if the class is being played well.

The priests have the same spell limitations as we do (short, expensive heal or the long, cheap heal, or the long, expensive heal) but don’t have the percent chance, nor are they limited by target the way we are, since our heals MUST be on the beaconed target.

d) The possibility of an internal cooldown exists. This isn’t unheard of. Eternal Glory‘s 30% chance to make Word of Glory not cost any Holy Power has a 15-second internal cooldown.

All said, I think the two-piece bonus COULD be great, but the mana returns are too low, we’re too limited in terms of our targets and, frankly, every other healer is going to get more procs off of their bonuses than we are, should it stay the way it is.

And now for the 4pc:

Raid-buffed, my average Divine Light hits for about 30k and crits for about 45k. So the 4pc bonus is going to allow me to hit my target for a bit more than that (given gear upgrades meaning more intellect), so let’s say about 38k and 52k for a DL hit and a DL crit in a raid with 4 pieces of T12.

20% of 38k is 7600 and 20% of 52k is 10400.

So my 4pc bonus will allow me to heal some random person near my target for 7600 or 10400 or some value in between?

- Will it be a smart heal or will it just heal anyone? A pet? Someone at full health?
- Define “nearby”

My concern here is that the radius will be small and that the heal will be random. If it is not random and if the radius is about the size of the old Glyph of Holy Light, this is a nice bonus. If it heals the player with the lowest health in its decently-sized ranged, I’ll be thrilled.

Sadly, my gut tells me it’s random, won’t care if the target is a pet or at full health already and will be pretty useless sometimes.

Having said that, no one knows how these bonuses are actually going to work. We’ll have to wait and see. I just really, REALLY hope these get some work done on them before 4.2 releases.
