duo vs Ele boss?

hi, could you please tell me wich duo team should be better to kill an ele boss? one of them should be a warrior or monk if posible. thx...

I would be thinking 55monk+ some damage dealer long range. Ranger with apply poison and melandru's arrows or something for conditions. SS necro with a disenchant if they have aura of restoration or whatever spell is where they get healed when you cast.

Basically the 55 monk tanks while a damage person kills, the 55 could use SoJ to help killing or just maintain the tanking.
