Midnight Raids Hub
Early in the expansion, players are looking for gear as fast as possible, so spending extra gold at the Auction House is a valid option. That means, though, these BoEs are likely an expensive purchase, with Heroic BoEs in the multiple hundreds of thousands of gold depending on your server.
Blizzard's addon changes have ripple effects that lead to something as commonplace as BoEs, however - normally, the Wowhead Client would be able to gather drop information to determine which specific mobs inside the raids drop these gear pieces. Since it's no longer possible to get specific NPC IDs via the client when loot drops, information can only be crowdsourced by players via word of mouth as to which specific mobs these BoEs drop from. It is currently believed to be only sourced from raid lieutenants like Blinky, so if you have more information, leave it in the comments below!

Interestingly, there's not a whole lot of consistency between gear slots this time around, though there are also a lot fewer special effect cantrip items to compete with this tier as well. Keep in mind that the items are BoE for lower difficulties only, with Mythic versions expected to remain BoP until at least the end of the Race to World First.
