Many other people foresaw our raid not being able to kill Festergut. They were wrong, and I hope we can prove you wrong too.
The frost resist epics are not the only source of frost resist. There are frost resist greens (which also have stamina, like the ilvl 213 epics, but just lack the sockets). More importantly there are other ways to get frost resist without giving too much in return: head enchant, bracer enchant (for Leatherworkers), cloak enchant. These might just be enough when added the 130 FR from aura or totem, but we'll see when we get there.
Another way to beat the frost breath is by not letting mystic buffet stack too much. If our tanks switch at every tomb, they might never be in any danger.

This is true. And also why I'm still interested in word from US to know if the raid IDs were wiped or not with the 3.3.5 patch.
