There is why it took you longer to kill him. Orb is an AOE spell not really single target. Before you say it has higher damage, it is far out weighed because of the Arcane power cost. If you would have used ray of frost, and maybe even frost nova to freeze him every once in a while, I think you would have taken him down a lot fast as that is better for single traget dmg.
