Just raided with a spriest who topped charts in every encounter, on HC xavius he did 350k dps meanwhile I did 250k. I am by no means a good spriest, I can get to 90-100 stacks, my haste is 35% and crit is 20%, I probably should be pulling better numbers but this guy has 80% mastery and he did a much better dps with much less effort (no stm).
Thoughts?
