Watch the video, note how the tank always goes to the claw (which has 1.8M health), just like in trash clearing, only difference is that Payback will be on one Flail and Grill will be on the other (there are 2 of them with 310k health each), once Flails are down Payback & Grill will start on Claw.
Ranged will be on eyes (there will be 5 of them with 710k each).

Also, we'll be doing 5 ping pongs each time and when you get Disrupting Shadows you must get away from the raid group by at least 10 yards before you're dispelled or you do massive AOE damage.
