Mythic + Dungeons for Season 4

I’m seeing references to two WoD instances, Upper and Lower Kharazan, two from Mechagon, and the two current ones from Tazavesh.

Is that correct?

I left BFA over Mechagon (I just could not stand the Disneyland-on-Krak design aesthetic).

I have no flight path there.

Not sure how to get there now as I’m on a character that never touched BFA and I have absolutely no desire to “relive” that wonderful experience.
