Frost, both 2h and dw, are amazing when burst is frequent and common, mobs to aoe are smaller and have less health, and have less opportunities for multi dotting.
Fights like Wind Lord heroic massivly favored dw frost compared to unholy. This fight in particular is interesting because on normal it is inverted. Longer aoe and a buff that has 100% uptime allowed for unholy to close the gap.
Its amazing how a fight like Stone Guards favored frost last tier, when a very similar fight in Council of Elders ( Less than 5 mobs stacked but for most of the fight) favors unholy, again, tuning.
Fights this tier that should favor frost if not for poor tuning or selection bias.
Jinrokh with frequent damage buff.
Council where cleave should trump aoe
Megaera with cooldowns up for every head and low health adds to burst on heroic
Jikun with low health adds to aoe and cds that should sync with every nutriment buff
Primordius lack of a pet helps when you have to kill your adds and passive cleave fluff. Unholy can actively fluff with cleave but plenty of ranking parses don't.
Raden is pure single target but has adds that need to be bursted down. Pillar of Frost should be amazing.
Festerblight has also caused an interesting development as a few fights that would normally favor frost, actually seem to favor unholy. ( Could just be tuning/selection bias).
My two favorites for this are the last 3 bosses on heroic:
Qon should favor frost since the aoe phase at the end is short enough that it can be done with cooldowns, however festerblight extension of diseases on the dogs as they fly away allows unholy to close the gap. Quite interesting.
Twins can perform festerblight and dot suen during phase 1. This allows for dots that continue ticking in phase 2. This favors unholy but what should favor frost is the adds that can be cleaved and bursted with cooldowns during and at the end of phase 1.
Lei Shen has frequent low health adds that can be bursted with cds however, people suggest the only dps that matters on this fight is in phase 3. Since unholy can roll powerful diseases from the start that last until phase 3, it became superior.
