Problem with King in the Mists drop table

Hello Exiles

I have finished 60 runs on T4 (8/8 atlas points) King in the Mists and got some interesting results about omen drop rate. And the result is that I haven't seen a single decent omen... How else are we supposed to get them? Cause I ain't seen one from rituals either.

Here is the quick summary of what I dropped:
ITEM: COUNT (ESTIMATED % DROP RATE)
Exalted Orbs: 65 (108%)
Chaos Orbs: 16 (27%)
Divine Orbs: 2 (3%)
Ingenuity Utility Belt: 19 (32%)
Beetlebite Velour Shoes: 29 (48%)
Pragmatism Explorer Armour: 2 (3%)
The Burden of Shadows Chiming Staff: 5 (8%)
From Nothing Diamond: 5 (8%)

(Regal Orbs, Vaal Orbs, Orbs of Annulment excluded)
