At this point, easy to 2-box if you want to farm augs/lamps.
All 3 named can pop in a random order it seems - so every time you run it, you might fight in a different order each run. They are all tethered to their spawn point and can't be pulled too far from it. As a result:
First named you can tag the 2 Brumes and the named will just path back. Easy split.
Second named - just watch out for 1-2 roamers and clear before pull. Just charge it and fight/
Third one is a bit more to do. First clear 2 Brumes at front of the room - no adds will come (you could probably leave these, but I've always just cleared). Next, invis up to the ramps by the king hail, and clear the 4-5 mobs up there) - this helps after named is dead. You can single pull the add that roams/circles the named from here too. Engage named and fight at spawn. Even if you camp a toon at the door and open it as the named dies, 2 mehpites will always spawn. Just kill them fast (if you want /ach for just 2 spawning) and hail to stop their spawn timer.
Win.
