Armor, dodge and resists already have soft cap and hard cap.
If crit chance, crit damage and IAS had soft caps and hard caps it would be much more balanced.
Armor and resists soft cap : 50-69% mitigation
Armor and resists hard cap : >70% mitigation
Dodge soft cap : 33-49% dodge
Dodge hard cap : >50% dodge
Critical chance cap should be : Soft cap at 33-49% range and hard cap from 50% and over.
Critical damage soft cap should be in the 200-299% range with hard cap at 300%.
IAS soft cap should be 50-69% speed of weapon and hard cap >70% speed of weapon.
By soft cap I mean when the diminishing returns begin.
By hard cap I mean when the VERY diminishing returns apply.
OR JUST REMOVE ARMOR/RESISTS/DODGE CAPS AT ALL
if theres no limit to damage, why do you limit our defenses?
