Avoidance Calculation for Plate Wearers
You need to have gmail to test this. You insert your values on the first page the calc will pop out on the 2nd. It will incorporate buffs that you would see in a raid. I have also included a separate buffs with approx uptime of mongoose and bladeward to see what the overall avoidance gain would be. The bladeward only assumes one stack and does not account for procs.
There is separate calculation pages for Deathknights, Warriors, and Paladins.
Note:This is only for avoidance and does not assume Boss level
EDIT: Thank you to Satrina for the base values.
Updated: So you can enter your naked Dodge, Parry, and Miss. For Nightelfs add 2% miss to talents or base.
Updated: Can now specify DK runeforging
Updated: Has 3.2 Calculations as well.
