We had our first pulls on council heroic last night, and the frostbite absolutely raped me every time. We tried the solo soaking strat, but I would die each try (and I would get frostbite each try as well). At first I went with stone bulwark totem + shamanistic rage, but have come to realize now that the shield isn't enough. So changed that to Nature's Guardian, to buy enough time so the healers get their CD's on me, but there was an attempt where it simply did not proc (since I went like 40% health to zero).
We then changed the strategy and have me stack with our rogue and monk healer in melee. If frostbite was on me, I'd stay stacked 7s, run out to let the debuff go away on the rogue/monk and pop my cd's, and then run in again 7s later. That went fine for like 20s, but then I died anyway.
So come to think that astral shift + shamanistic rage is good for the first 6s, but after that it's gonna be a problem.
I'm specced into prime elementalist, so I could use reinforce / harden skin from the earth ele, but that would mean I can't pop fire elemental at the pull with lust/pots/procs.
Another option I have considered is using the tol barad resistance trinket (it's a -15k simmed dps loss), which gives 400 frost resistance for 10s, though not sure how that translates at lvl 90. We seems to be ok on dps, so that could be worth it.
Anyway, how did you guys deal with the frostbite, and did any of you solo soak it?
