Positioning is important, don't give Deaman the higher ground advantage or he will pummel you. Bring an RC monk. Don't underestimate the pets. Bring tons of interrupts and weakness. When one boss is down, the other will use resurrection signet. Interrupt it or just kill the rezzed boss again. I did it with 2 people + heroes indeed, I think with H/H this one can be a real pain.
Fun is, this mission PUNISHES people for bad positioning (Argo uses AoE spells, Aurora uses barrage, and deaman uses choking gas), so if you only use heroes there is a possibility to flag them away from eachother. Hench however, ouch, just ouch. Other fun is, under ideal circumstances you need a dedicated interrupter, a defensive char (think wards and water snares), an RC monk, a curse necro and yourself, that's 5 spots taken

.
Seeing your profession is warrior, I hope you already figured out that tank builds are a no-no in this mission, you need firepower, I just point it out in case you didn't know yet.
I don't say it's impossible with hench, but it sure is hard. 1 thing to cheer you up, once you pass the arena the rest of the mission is surprisingly easy.
Edit: listen to tmakinen, aegis is more or less a must in every HM mission

Just dont let deaman near your monk.
