We deal with portals, with DPS taking portal to center and tanks taking portal to edge based on the numbers in the diagram.
Ranged and heals stack at a spot behind the route the tanks are going in, so if we're going clockwise on this diagram, ranged/heals stack at 0, then 1, then 2, and so on as Xymox is moved forward each portal.

Stasis traps from Nathria repeat, but there are fewer and they cannot be permanently purged. They'll rearm themselves.
Periodically, a big fuck you ring will go from inside of arena outwards or outwards in, and we use portal to dodge that. It's pretty much identical to Shuri from Streets' final boss. After the ring, DPS run towards green and a tank will run towards circle to handle a draw in effect similar to Nathria.
There's an add phase where we burn down two top prio adds and handle minor raidwide, then fight repeats with just more frequent rings as we go on.
