History
Added in Patch 3.0.2 as the 51-point talent for Arcane, Arcane Barrage was designed as a single-target instant cast spell with an unusually high spell power co-efficient. Arcane Barrage's intention was to be used alongside Arcane Blast in order to consume its debuff and allow the Mage a way to conserve mana without interrupting casting (much like the spell does currently with Arcane Charges). However, any other Arcane damaging spell was capable of consuming Arcane Blast's debuff, and often Arcane Missiles was used instead as it had superior damage and no mana cost. This led to the spell being seldom used in PvE prior to its redesign in Patch 5.0.4.
