Which class has currently no way of dealing with Silence and can't act with it?

Evoker (Whispering Cant only works for mage base spells and increases their costs by a lot), Rune Mage, Tactician, Magic oriented Ghosts, Hexer can only inflict silence not remove it, Ranger is another, Priest/LB/Aqua cannot remove etacof thus silence will stick.

All in all, currently you are subjected to slotting Heron Feather always as it's become pretty much mandatory for magic builds.
