Did this twice, 1 pass 1 fail.
The pass was with a Repeat offender team consisting of 2 brutes a defender a blaster and a dom (i think). The second mission was hard because it was on invincible and the one guy who knew about the EB after every cyst and the massive explosion chose not to spoil it for us. The final AV fight was pretty easy initially as one of the nictus practically died from intimidation. It got rough for the next few minutes, but they couldn't kill us and eventually we just split the nictus and ate them one by one.
The Pug fail team was something like 4 blasters, 1 Bots/traps, 1 Earth/Kin, 1 D3, and a Grav/Rad. Naturally the Rad left right before the last mish so we lost a blaster he was sidekicking as well. The first few spawns were hard for us as the mobs were out of control, in a couple minutes we found our groove, and steam rolled it. I died at least 20 times, but I was usually rezzed by time Build Up recharged so I was happy. Then we got to the final AV.... 3 of us at least talked like we knew what we were doing. The MM was tanking the AV, and the other 5 of us wailed on a single Nictus. We couldn't put a dent in it.
