Hello there everyone.
I've made a simple .exe file you can use to calculate what to roll on your weapon. Type in just a few information about your weapon and it'll show you what to roll to get the most out of your weapon!
You're welcome to write some feedback here or add my battletag.
Currently working on extention to calculate if Armor, %life or Magic res is better for your character.

Just got a really nice reply from the US battle.net forum with a virus check on my file.
