Fids gets (limited) free ward finding since they changed his passive. If you can see an enemy champion or minion within 1000 units while you're hiding in a brush, check them for the Dread debuff - if they have it, then you know you're visible to them thus the brush must be warded.

Slightly limited in usefulness, but it's an interesting trick.
