My arcane mage is only an alt, but it's the alt I enjoy the most. Since the prepatch I've seen several arcane mages whose rotation consist on spamming Arcane Missiles nonstop, not a single Arcane Blast. I asked one of them intrigued and he replied that it does more dps than the standard rotation, and that's even stronger to do so in the mana burn phase, but he didn't explain me why is that. He also didn't explain me how he managed mana spamming Missiles.
What am I missing here?
Thanks.
