Frost Blast is removed, and Ice Barrier boosts Frost damage

Frost Blast, the slowing spell added in the October 15 build, is removed in the November 2 notes.

• Arcane: Arcane Blast’s mana cost rises 100% per stack (was 175%) and each stack gives 12% of Intellect as Spell Damage (was 15%), lasting 18 seconds. Missile Barrage moves to row 2 and, in a fix, is now spent when the Arcane Missiles channel starts (it was spent at the end), and Clearcasting is no longer spent on Arcane Missiles while Missile Barrage is active. Arcane Resilience moves to row 1 and takes 3 points, for armor up to 75% of Intellect. Arcane Focus is removed, folded into Frost’s Precision.
• Fire: Incineration takes 5 points for 10% crit (was 3 for 6%), Critical Mass goes back to 3 points for 6% (was 5 for 10%), and Improved Fireball becomes Accelerant, which also cuts Arcane Wrath’s cast time by up to 0.5 seconds. Improved Fire Blast moves to row 3, and a fix makes Ignite apply to all of Flamestrike’s damage.
• Frost: Piercing Ice is removed. Ice Barrier now gives 15% more Frost damage for a minute when cast, plus 5% while the barrier holds. Frost Warding raises the absorb of Ice Barrier and Frost Ward, and instead of reflecting spells it can fully negate one without draining the Frost Ward. Elemental Precision is renamed Precision and is a 3-point talent again, 2, 4 or 6% spell hit. Ice Lance shares an 8-second cooldown with Fire Blast and its bonus damage to frozen targets returns to 300%, and Winter’s Chill adds 20% Cone of Cold damage per stack.

Why it matters: Frost Mages have a reason to go deep in the tree for raids, and the slowing spell from mid-October is gone.
