Assuming holy paladins are in the mix, a popular healing strategy is to beacon the tanks and heal the pets in the raid, because heals from Beacon of Light do not stack Deep Corruption and pets don’t receive stacks of Deep Corruption.
The question came up, the other day, about whether or not a hunter should use a Tenacity pet, who has the Blood of the Rhino talent. Would the lower DPS be worth 40% extra healing to a pet and then, ostensibly, 20% extra healing to the tank through Beacon of Light?
This was a popular strategy back on Valithria Dreamwalker. You would park a turtle or some other Tenacity pet with the same +healing talent basically on top of Dreamwalker or right next to her and you’d heal the pet for extra healing done. Unfortunately, this stopped being viable eventually when they fixed Blood of the Rhino to only affect the pet and no copied heals from that (ie: Beacon of Light).
But that was back in 3.3. Did 4.3 mean this was somehow working again?
I bothered Daey to get on his holy paladin, Saerani, while I was on Kurn and we experimented with him beaconing me and healing my pet. The first pet he healed was my cat, Whisper, who has no +healing talents at all, being a Ferocity pet.
So you can see here that Daey hits Whisper for 55355 (crit). This bounces to me for 27677, which is just half of that heal. (Yeah, I miss 100% Beacon transfers, too!) The same with the 27672 hit, that gets me for half — 13836. That is totally expected. This is the control for the experiment. Now let’s look at Daey healing my bear, Fozzie.
First, note that the non-crit heal hits for 40,102. Based on the heals Whisper got, it’s clear that Fozzie has the Blood of the Rhino talent if it hit him for a 40k non-crit.
But then you see that the heal to me was only 14322.
14322 x2 = 28644 x 1.4 = 40,101.6 = 40,102.
So the original heal size, without the Blood of the Rhino bonus was 28644. With the 40% extra healing, we get 40,101.6 (rounded up to 40,102). If this +healing did transfer through Beacon of Light, we wouldn’t see me being healed for half of the original heal’s size. We would see it be half of the final heal’s size. The final heal was 40,102, so we would be looking for 20,051 as the heal that I got. But alas, I was only healed for 14,322.
Let’s see how this holds up with the next heal.
Fozzie is healed for 71865. I get healed for 25666.
25666 x2 = 51,332 x 1.4 = 71,864.8 = 71,865
Yup, same deal.
So it’s quite clear — Blood of the Rhino does not transfer any extra +healing from the pet to the Beacon of Light target. As such, on the Heroic Yor’sahj the Unsleeping encounter, I do encourage you to beacon the tanks and heal the pets, but don’t gimp your hunters’ DPS by forcing them to bring a Tenacity pet to the raid. Their regular pet will do exactly the same thing a Tenacity pet will.
