When it comes to 25 man raiding at least.Neither HS or GHW are dominant heals... so neither of these numbers are of great concern to me.
I find chain heal to be a superior option under almost all other situations.
And feel free to lightning bolt plenty in a fight.
While saying that GHW and HS are not dominant heals in 25man is valid, I have to disagree with that we need to overlook their value and contribution in healing to the point that we shouldn't even be bothered with doing math for them. This whole concern was raised due to the fact that the bonus of our tier 14 2pc which seems to be rather underwhelming. The point of this thread is to theorycraft Resto Shamans for both 25man and 10man, it would be unreasonable therefore to overlook any spells and avoid calculating their value nomatter how much they are used in any situation.
Results more often than not end up surprising us, so I would love to see a chart of RT-HS-HS vs CH-CH-CH , I think it would be very interesting to compare their HPM and HPS .I will put it in my todo list for the week to come.
This is another chart I would love to see, a comparison in LB's mana return to casting Rt-HW-HW-HW maybe. Resurgence percentage returns have gone up from Cataclysm, for example Cata HW = 115% vs MoP HW = 148%.
