Omens suck and suggestions

Right now most of the omens do the same thing, makes your crafting currency target a suffix or prefix, so the question is why are there so many of them?
Why not make 1 omen for prefix and 1 omen for suffix that works for all currencies, including ones that don't have an omen associated to them yet, like Divines.

And secondly i think we should get new more interesting Omens, like one that makes next Annulment orb remove all affixes and turns the item normal. So instead of completely removing scouring orb, maybe it should be really rare. Maybe another omen that makes next Chaos Orb target a resistance modifier and replace it with another resistance modifier of the same tier.
