Completely serious question- is holy dps actually better than shadow for this fight? You have 7 targets, and holy chakra boosts mind sear and halo to outrageous levels such that you're out-dpsing a shadow priest. You also have a lot of downtime on heals apart from bladestorms, so you have decent utility heals as well.
On an LFR I did around 150k dps on that fight (mind sear multi, then swp/hf/smite when it's boss only.) On single target fights I do about 70k dps which is pretty reasonable considering my healing utility.
I realize this is probably the only fight this tier where this is possible, but has anyone tried this?
