10:1 is the ratio but the place holder values are dictated on the class the gamer is using.
Int based 10 AR = 1 armor. this means armor is more value
DeX/Str based 10 armor = 1 AR.
Barbs exclusively hold vit/life % more valuable than elite dmg reduction. because of blood funnel aka "life steal"
elite dmg reduction is worthless IMO because youll either go full dmg with a HF ammy or have an immunity ammy.
You have a higher chance of dying for trash throwing arrows at you than getting 1 shot by an elite affix.
