Sabway necros (with little modifications).
Ranger Hench (interrupt)
Mesmer Hench (Illusion)
Monk Hench (Protection)
Ele Hench (fire)
Me being the standart GolE+HP HB build monk.
Everything went fine up to level 3 without deaths (expect the norn ally warriors died many times), up to the point where that boss wurm with 3 other wurms are. I was being little lazy with the flagging (which was main reason it failed), all 4 wurms poppped in middle of the group doing their aoe snares and dmg wiping the whole group.
Now i think i could at least made it to the level 4 if i just had flagged the heroes so not everyone takes the damage, but i'm not sure if the setup would have worked in L4/5 or for Frostmaw the Kinslayer. And obviously there isn't that many corpses for the minionbomber, however he was controlling 9 minions after first few groups in each level, so it wasn't that bad.
Now i was wondering if there is a known H/H setup to do it (normal mode would be enough), or if someone got a tested setup that they are willing to share.
Thanks

edit:
I also could play as Warrior, Ranger or Dervish for it, though only my monk have geared/runed up heroes.
edit2:
I was thinking of something like this instead:
Interrupt Gwen
BHA Ranger or Hudred Blades Koss
Curses Necro
Me being smiter's boon smiter. (reversal of damage, smite hex, smite condition etc.)
Henches:
2 monks, 2 eles.
I've never done this instance so i don't know really what to expect from the last 2 levels.
