Just to add another log (though I doubt there needs to be any more evidence for weird spellhit things going on with sPriests)
Wow Web Stats
21,5 million damage with 170 spellhit, 0% misses. I counted 9 MF whiffs over the 52 pulls. 6 of them on Shardron, 3 of them in a row.
What seems pretty interesting to me is that Shadow Torment missed with 17,5% (yes, I should be more awake and not try to kill myself... I know). I guess it just totally ignores any player's stats like spellhit (and class), but that would again hint to unchanged miss-values.
