I understand that Cutters and frigates have stasis resist with Mk up (cutters 50% / frigates 80%). Maybe a Resistor could add a max at 15%?(lv1 5% / lv2 10% / lv3 15%). Of course you wouldn't want to make it 20% because the frigates would render stasis weapons obsolete. But they still have that small percentage of unlucky fortune. But if it were a resistor slot it can be fitted to most classes of ships that have such a slot. Which could give other classes some stasis.
