Quote from SaikoDrakieany idea how + and - work together?
for a wizard they have energy_armor giving +65% armor and glass_canon giving -10%, that becomes +55% right?
That makes sense, but to be sure you'd have to experiment the way I did with my barbarian.
Then again, after i concluded my experiment I later found a post in the barb forums that confirmed my findings. Perhaps the wizard forums have figured that out. good luck.
edit: we get the same numbers now, lets hope we're both right. I like yours better so now i'm using yours exclusively. i especially like how it calculates percentage changes before you click them, AWESOME feature.
