Now, the CM mechanics are a different in that we freeze reducing incoming damage with periodic timeouts of diamond skin if not managed well or just bad elite affixes. After clearing a big horde of monsters there are quite a few globes sitting around. I'm thinking that the globe production / reduced incoming damage would have a very similar result and greatly increase the survival. Globes give you a burst of life regen that runs for a period time. With elite packs, there are usually more globes produced and can possibly give enough life regen to keep standing.
I'm thinking to try for about 14 yards max pickup and around 20-25k globes. Let me know if you are doing this already and how it works out. Thanks!
