Then Arcane Barrage, some people have said not to use this, but I strongly recommend at least WoTLK Gold getting Arcane Barrage because when you're being forced to make damage on your move Fire Blast isn't enough to right kind of make up for the damage done by the move.

If you're at all far from the intended target. Fire Blast, just single GCD and that's it. Also that if you have Arcane Barrage it is possible to use Arcane Barrage or Fire Blasts Arcane Barrage, and Arcane Barrage alone on Heigen is going to be quite damaging, since when you're performing the dance, you're likely be able use Arcane Barrage and be used to trigger an Arcane Missiles to send fast Arcane Missiles off in between the blob waves. So, Arcane Barrage, I would highly recommend taking it up.

Then, you can do whatever you like, you could, you could pick up three points and suit in your mind if you desired to. This is my opinion on the spec. A lot of people like the idea of having one advantage in this it is that you can simply perform any mechanical task that is 30 yards and arrange them in any way you want. I personally am kind of thinking of something like this. But that could also change.
