I don't plan to use the Necklace of Mystic Eidolons. Although I will point out that the necklace does not have fortification and with the loss of the Mythic Minos Legens for Sightless, Shadowscale armor becomes the only source of fortification.
I hear ya. I think I acquired every set of Intricate Field Optics with the specific stat that I was looking for from the auction/shard house. Sometimes it has taken months before the specific set I'm looking for even shows up, and then it's usually for a ridiculous amount of shards. And in the meantime, I have no luck farming it from Tor.
Strange Tidings is for both deception (which the build currently lacks) and the sneak attack damage. With the high rate of attack on this build, deception should proc often enough to be of benefit. Not only do you get the additional sneak attack damage when deception procs, but you get the defensive benefit of the mob turning away from you. And 16 sneak attack damage is nothing to sneeze at.
By using both Strange Tidings and The Band Immaterial, I'll be losing seeker 12 on Consuming Darkness. So the Pendant of Quiet Movements is primarily for seeker 12. Also, the insightful will save 2 will not stack with insightful saves 4 on the Epic Ethereal Bracers.
