I'd be fine with buffing the duration of Infliction-check Silences.

I would not, however, buff the duration of Absolute Fear's silence. Nor is the skill 'useless' enough to warrant buffing a Silence that can be slapped on without a care for status resistance, unless you're telling me that somehow, everyone and their mothers runs the entire Bravery talent and everyone and their mothers would run Heron Feather over either a major stat-booster accessory, Sayakana, or any sort of Elemental Resistance booster.
