Tell your healers to be better. If you have a white mage and a scholar you can get around 2k+ damage mitigation prior to the death sentence, and that isn't counting any sort of buffs the tank may use. I don't think my group has gotten any sort of tank item outside of the shield and a ring, and there has been no trouble healing them through any phase of coil including up to the phase of Twintania we are on. You just need need to adjust and get the mechanics down and be proactive instead of reactive.
Also, I like how absolutely none of this thread tries to put together any sort of beneficial response to the OPs question, and is instead just people attacking one another.
