I'm including Gift of Nature which puts it around 200%. To go all out you'd also have to take into account that all healers are not healing the tank for the same amount, but that is somewhat overkill for spirit vs healing, since we allready know its not a good idea in the best case scenario. Raven idol while in the tank group on the other hand...

Please take this with a grain of salt since its highly variable, but should give a general idea of which idol to use when. I’m only focusing in on tank healing because thats the assignment in question, any raid healing with this assignment is icing on the cake, but should not be focused on. Common assignments on the tank are myself and 2 Pali’s, but I included Priests since they are the swiss army knives of healers. Some general rotation % as well…

Coefficients (with talents included)…
Druid (85% Triple Stack Lifebloom 10% Rejuv 3.5% Regrowth DH 1.5% Regrowth HoT)
Triple Stack (HoT) = 2.025
Rejuvenation = 1.16
Regrowth (DH) = 0.3188
Regrowth (HoT) = 0.918

Pali (85% FoL 15% HL)
Flash of Light = 0.479
Holy Light = 0.800

Priest (75% Gheal r1 10% Gheal r7 15% Renew)
Greater Heal r7 = 1.114
Greater Heal r1 = 0.811
Renew = 1.25

Shaman (100% Earth Shield)
Earth Shield = 2.178

It’s been established that queen is 67heal (thank you buggy idol) and raven is 44heal. Plug that in to find avg heal bonus and you come out with…

Queen = 115.3
Druid = 115.3
Pali = 0
Priest = 0
Shaman = 0

Raven = 271.98 (using Druid, 2 Pali, Earth Shield)
Druid = 81.49
Pali = 46.08
Priest = 48.58
Shaman = 95.83

At first glance, it seems like a no brainer to go for raven, but take a closer look. Shaman gets the biggest bonus? This isn’t accounting for the actual heal throughput (effective + overheal) on the tank. Another variable that is up in the air is hot overheal, from the tracking I’ve done I value it around 50%. So generally you get something like this breakdown on a tank…

Druid =42%
Pali =28%
Priest = 28%
Shaman = 1%

Account for this you end up with…

Queen = 48.4
Druid = 48.4
Pali = 0
Priest = 0
Shaman = 0

Raven = 60.92 (using Druid, 2 Pali, Earth Shield)
Druid = 34.22
Pali = 12.90
Priest = 13.6
Shaman = 0.96

Please note that if your assignment is the tank and you only have 1 pali/priest you have about the same benefit, so at that point you’d probably want to go with queen to boost raid healing with your extra gcd’s.
