#258 Missile Barrage proc can benefit two casts of Arcane Missiles

Status: Fixed · Area: Classes & Specs · Mage

By casting Arcane Missiles again mid-channel, the second cast gets a free, shorter Missile Barrage version firing only 3 missiles.

Current behavior

Since Missile Barrage is now consumed in the end of AM channel instead of start, it is possible to press hasted AM, fire 3-4 missiles and press new AM. Second channel of Arcane Missiles gets cast time benefit (2.5 seconds instead of 5), costs 0 mana, but fires 3 missiles instead of 5.

Expected behavior

Interrupting MBar Arcane Missiles by using new Arcane Missiles should result in new cast being normal version of Arcane Missiles (5 seconds, actual mana cost)

How to reproduce

1. Use arcane missiles with missile barrage buff active
2. Use arcane missiles again during the channel
3. Get new 2.5 second 0 manacost cast
