Looking at my character's combat attributes, I noticed that the Status Effect (or "Mez") Resistance I'm getting from enhancements and sets is less than it says in their description. For example the Unique "Aegis: Psionic/Status Resistance" enhancement is supposed to reduce the duration of status effects by 20% but according to the Combat Attributes window only reduces by 16.67%, same with all other set bonuses.
Is this intentional?
