Best 4 person all caster/priest group

[Duik]

@DSM (Don't Say Mage)
You mention a lifetap at 405 mana and 720dam. Thats 1.777 efficiency!
That would be true if it was just damage.
It does 720 heal as well so i propose 1440 damheal @ 3.555 efficiency. But whatever.

Given a choice, if no clr id slum it with a shm.
I love me a wiz but a mag seems to offer more in this scenario. With a mag (malo) id go a druid (especially if animal charms) instead of a shm especialy pre 60 or no torp.
Lets face it, group of 4 played well will drill holes in any group content.
The difference will be the quality of the banter.
