Fire leveling order 10/36/5 Guide's pick, untested
Arcane: Wand Specialization 2, Arcane Focus 3, Arcane Concentration 5
Fire: Improved Fire Blast 2, Incineration 3, Improved Fireball 5, Ignite 5, Impact 3, Burning Soul 3, Pyroblast 1, Heating Up 1, Master of Elements 3, Critical Mass 5, Blast Wave 1, Fire Power 3, Combustion 1

With the Talented legacy perk every step comes up to five levels sooner.
Fire, level 30 0/21/0 Tested in beta
Fire: Improved Fireball 5, Ignite 5, Flame Throwing 2, Burning Soul 3, Pyroblast 1, Improved Scorch 3, Heating Up 1, Blast Wave 1
Level-30 Fire build: Heating Up at 25, Blast Wave at 30. Alternatively, take Incineration 3 instead of Flame Throwing and Blast Wave. Order: the Fire levelling order, keeping this build's talents; Flame Throwing and Improved Scorch, which that order skips, go in where the tree allows.
Fire, level 60 (Fireball, projected) 16/31/4 Guide's pick, untested
Arcane: Arcane Focus 5, Missile Barrage 1, Magic Absorption 2, Arcane Concentration 5, Arcane Impact 3
Fire: Incineration 3, Improved Fireball 5, Ignite 5, Burning Soul 3, Pyroblast 1, Improved Scorch 3, Heating Up 1, Master of Elements 1, Critical Mass 5, Fire Power 3, Combustion 1
Frost: Elemental Precision 4
Fireball build, 16/31/4: Combustion, Fire Power and Critical Mass, with Arcane Concentration and Missile Barrage for mana and Fireball procs. Beta theorycraft. Order: the Fire levelling order, keeping this build's talents; Improved Scorch, Arcane Focus, Magic Absorption, Arcane Impact and Missile Barrage, which that order skips, go in where the tree allows.
Fire, level 60 (Frostfire, projected) 0/29/22 Guide's pick, untested
Fire: Incineration 3, Improved Fireball 5, Ignite 5, Burning Soul 3, Pyroblast 1, Improved Scorch 3, Heating Up 1, Master of Elements 1, Critical Mass 4, Fire Power 3
Frost: Elemental Precision 5, Ice Shards 5, Piercing Ice 3, Frost Channeling 2, Ice Lance 1, Ice Block 1, Shatter 3, Fingers of Frost 2
Frostfire Bolt build, 0/29/22: it gives up Combustion to reach Shatter and Fingers of Frost, because Frostfire Bolt's slow is a Chill and the bolt counts as Frost and Fire ("you can double dip with Frost talents"). Beta theorycraft, and the most speculative build here. Order: the Fire levelling order, keeping this build's talents; Improved Scorch, Ice Shards, Piercing Ice, Frost Channeling, Ice Lance, Ice Block, Shatter and Fingers of Frost, which that order skips, go in where the tree allows.
