Yeah, when it comes to logs that have already been analyzed and organized for us I agree it’s easy and fine to just look at where specs fall and what the difference in average dps is from bottom to top (15-20% seems a little high by the way). I also see that frost is average for mythic. Not really sure what that has to do with the point I made. I do get frustrated seeing you make an argument by throwing out statistical terms that you don’t understand. It’s dishonest and reeks of insecurity. Probably just me projecting some existential angst, what with the whole post truth trump world.
Standard deviation is straight forward to calculate. You can plug in the numbers for average dps across classes and see for yourself that they (probably?) don’t “fall within one standard deviation”. Assuming the numbers are close to normally distributed, you’d expect to see that about two thirds of classes fall within one SD of the mean.
