I'm working towards http://www.wowhead.com/talent#oZfVc0RhIhVubhcthI0sRzh (level 76 at the moment). It's intended solely for 5 mans, and that horrible grind you have to do to farm emblems (farming 3 times if you want PvE, PvP and BoA gear).
It completely neglects fireball to the point I don't even bother casting it, and use scorch instead. That isn't too much of a problem in 5 mans where things die too fast, or you have to move or get interrupted too much to finish a fireball cast.
The AoE DPS that the build is capable of is, as Mozared said '*SICK*'.
.
You open by dropping living bomb on as many of the mobs as possible, follow up with the 2 highest highest rank Flamestrikes, and then Blizzard. By the time you've got round to Blizzard and it's chill is giving you masses of crits from a huge pile of DoTs, chances are the mobs are getting into the 35% health that leaves them open to another 12% damage thanks to Molten Fury.
Then the Living Bombs go off.
You can pull off stupid amounts of damage with next to no chance of over-aggroing, because the build up is slow enough to let the tank get a lead, and even if you do pull 4-5 mobs during the Blizzard, they'll be slowed, you'll more than likely have a Hot Streak proc to use on any caster, and you can just Frost Nova and drop another Blizzard on the remaining melee.
Nothing short of a DK built for the same purpose comes close on the meters, and they run the risk of pulling aggro, as their DPS is more front loaded.
I'm wondering if it would even be possible to put the scorch debuff onto the mobs as part of the opener for another 5% crit chance (may well be possible if they have a slightly higher healthpool than the mobs I'm facing while levelling, to give me more time to get to the 35% Molten Fury effect).
The only problem is the huge amount of mana you get through. I'm glad I've got engineering for the Nitro Boosts, otherwise I'd be miles behind from all the sitting and drinking I have to do.
