I was just playing with this:
Me (VoS Dervish)
1 healer Monk
1 RoJ Monk
1 Minion Bomber
1 SoGM Rit
1 N/Rt healer
1 Panic Mesmer w/Blood support
1 Psychic Instability/Fragility Mesmer
...it works pretty awesome. I was doing Stygian Veil and only died because I suddenly lagged massively and rubberbanded halfway across the map and aggroed like three mobs, grrr.
I will definitely try out more combos tomorrow, though

this is fun.
