mage missile barrage macro (request)
There is another reason you don't want to stopcast your AB. Arcane Missiles only do mediocre damage unbuffed. You only want to use them when they have the full four stack of arcane blast buff and the haste buff for the proc in an ideal situation. I will typically use them with or without the proc after the fourth AB because the AB will not stack any more.
Caveats: If I cannot get another AB off before the buff stack will drop due to movement, whatever, but I do have the barrage proc and at least two stacks of the AB buff, I will use AM early. If the mob is low health and I cannot get off an AB, I will use Arcane Barrage to try to get a proc and missles to squeeze in a little more damage.
