actually, i went frost to help on our first cho'gall kill. i could practically solo the Blood of the Old Gods, easily doubling our surv hunters damage on them, so everyone could just tunnel the boss. maloriak also has adds that need to die fast, and while not as hard, there's certainly more than 1 fight where burst AoE is needed. 40% less of 20-40k crits is still 16-32k, i still think it'll be nerfed further.
