since these are 5.0 you should not really bother with anything else besides the first "optimized tables" which tells you how you should gear your toon regarding the spec you play.. but its rather for objective purposes, experienced players usually have their own way of playing, some use more alacrity, some use mastery stim with lest crit/ala stats, tanks use far less defense etc..
those other tabs in my opinio are for the miners purposes to show how he did those calculations..
and if im not mistaken, there was a sheet with 5.2 numbers ie 248 gear.
