Frostbite Immunities

Prepping our tactic for council 10; we'll be 2 healing so it's extremely important to plot out our immunities correctly.

Assuming the following work:

Holydin: Bubble
Mage: Ice block
Moonkin: Cloak- symb
Shaman: Ankh

Do the following work?

Hunter: Deterrence
Moonkin: AMS -symb
Warlock: Dark bargain???/other?
Do monks have anything?

I'm planning to aoe heal the 1st, immunity the 2nd and 3rd if possible; if not let the 3rd die and CR. Tips?
