Just did this with 3 people, I was BH tank, DPS juggernaut, and healing sorcerer. We pulled out a healing companion to help us.
I cycled, and aoed like mad generating threat on all three. Juggernaut started with medic, then massey, then the captain.
I couldn't time any interrupts properly, and I don't recall anyone interrupting the medic.
We got through it after the 5th try. If we had a full group of four I suspect we would have done it sooner.
