I find that the best guarantee is to pre-heal and suffer massive overhealing, not reactive healing on each character with a separate keybind. If you have an AOE heal, spam it regardless of if anyone is taking damage. If your healer isn't capable of sustaining the mana for this, you need to gear for MP5 until you are. This fight can become a very mindless tank and spank if you pop frost resist aura and just mindlessly spam healing. The time you spend moving your characters around might be better spent healing since, as you said, the frostbolt is really the thing that nails the coffin on you in the end.
Since I started moving out of the blizzard, I have yet to suffer a single death on this encounter. Relying on gear so you can mindlessly spamheal seems rather inefficient to me. Simply moving out of the blizzard (which takes like 2 secs) and throw a quick lesser heal when someone get low is not only easy, it's also more efficient and doesn't require any specific gear (I did the encounter in 90% blues the first time). Also, in order to use chain heal efficiently you'll have to target it anyway, which brings us back to healing hotkeys.
