My 10m group recently began putting in unsuccessful attempts on Nefarian (mostly problems kiting adds in phase 1).
I was looking at our logs for two recent nights of raiding, specifically at Electrocute damage. I've noticed on nights where I run as Discipline more (and more absorbs in the raid), the amount of damage resisted is less than when I run as Holy. Average amount of damage resisted on a Crackle when I'm Holy is about 20% higher than when I'm Discipline.
My question is about how damage/absorbs/resists are calculated. Does the game calculate the amount resisted as a fraction of the total damage or does it calculate the amount resisted as a fraction of the damage after absorbs? If the latter is true, it's a penalty for me to be Disc as the resists are taken from a smaller number after my shields are calculated. I'd rather benefit from a larger resist and heal up raw damage as Holy than work with pre-shields, a subsequently smaller resist, then healing up the difference.
Ugh, sorry if this isn't clear. Thanks for any guidance here!
