These are ingame numbers, but they demonstrate a problem of the system: If an enemy has for example 200 magic armor and 800 physical armor it would have a cc resist chance of 80 % if the magic armor has been removed. The system works only if the armor values are roughly equal, because the attacker has to damage both armors if one of them has a much higher value. This increases only the length of the combat encounters.
I already answered that kind of questions that is why i said - read forum
Mages have alot of physical dmg spells Even with 80% resist its good to fight vs such enemy etc etc read forum
