in attributeslib.cfg there isnt a way to use the armor toughness in the formula, just generic armor.
so, it would be great if there was some way to reverse the new calculations back to vanilla
(The protection damage reduction formula / The a-value formula / The armor damage reduction formula )
and it would be nice if there was an easy configuration like
#Do you want the damage reduction to be Vanilla?
#Default: false
B:"Enable vanilla damage reduction"=true
