Build 8982
Right, updating stuff. Or not. Missing information.
Does Torment of the Weak do anything at all? And does it work on bosses?
Assuming for now that it doesn't. Not that it matters much, since every spec is pushed into 14+ Arcane now anyway.
Spending 18+ for Torment is possible for all specs, Frost being pretty tight on points though.
Assuming Spell Impact incrases Fireball damage by 6%. It adds 6 damage in game right now.
Assuming Ignite losses for Fire specs. In particulate, a Pyroblast Ignite will not trigger if the previous Fireball crit.
Numbers always assume a fully raid-buffed Naxx-10 kit.
DPM and mana consumption numbers usually don't include spirit regeneration, because that is not spell-dependant and usually misleading.
Spirit
Spirit regeneration has be reduced one patch ago.

In the Naxx-10 kit, you went from 140 MPS to 110 MPS while not casting.
45 mp5 loss with meditation, 75 mp5 loss with mage armour.
Arcane
Arcane Blast spam
3811 DPS, 4.5 DPM; 839 MPS (733 MPS after spirit regen and Mage Armour)
You're spending your mana twice as fast as you can drink up again.
Barrage/MBAM rotations with Fireball / Frostbolt (Frostfire Bolt is about 400 DPS lower)
3680 / 3610 DPS, 10.7 / 11.1 DPM; 303 / 285 MPS
Frost
Deep Freeze on the second charge becomes obsolete at 1600 spell power.
Ice Lance to get a third charge gets outscaled at 1900 spell power.
Deep Freeze to get a third charge remains a damage gain until 5200 spell power.
Frostbolt spam
3091 DPS, 16.4 DPM; 189 MPS
Frostbolt cycles with FoF-DF and BF-FB and Arcane off-spec
3270 DPS, 18.9 DPM; 172 MPS
The Water Elementals adds 588 DPS when it's up and assuming it is hit-capped.
3611 DPS all combined if the pet doesn't die.
Fire
We're assuming Fire specs into Arcane as off-tree. No more Icy Veins.
Also, assuming the 3% hit are bought via gems. It'll be less loss on in reality.
Fireball spam
3488 DPS, 17.5 DPM; 199 MPS
Living Bomb and Frostfire Bolt as DoT spells
5806 DPCT, 8.6 DPM; 676 MPS for Living Bomb
3379 DPCT, 22.1 DPM; 153 MPS for Frostfire Bolt
Fireball cycles with Pyroblast
3752 DPS, 17.4 DPM; 216 MPS
Fireball cycles with Living Bomb and Pyroblast
3929 DPS, 15.4 DPM; 256 MPS
What's new?
Nothing really. Arcane Blast is still useless. Fire doesn't actually look that mana-hungry any more.
If Torment turns out useless, Fire may actually grab Meditation from Arcane as well.
The placement of Spell Impact for Fire specs is a direct buff to fire that adds little to nothing for Arcane and Frost specs.
Even with the changes to mana regeneration, a full Fire Rotation should be sustainable.
