Ixchel's Torment - 'Additional Socket'

This strongbox loses a lot of the excitement when it rolls the 'additional socket' mod. Oh boy, the best I can get is a random unique with no quality and a single socket that's already corrupted. Is it even worth it? Additional implies extra. This is a sought after corruption on some items because two or three sockets is huge but off this box it's just sad. Please adjust to roll as 'max sockets' off this rather than +1 on the default of 0.
