The reason we use the palm

So you'd have to essentially be waiting for about one-half second WoTLK Gold , which could go up to in order to make use of this macro as well as use arcane powers which is likely to result in an DPS loss having to wait like that, or you're going to use everything in the macaroni Arcane Missiles is going to be destroyed without arcane power, which is not the best option. This is why we apply it after the second casting and you then hard cast the other AV so that you're able to directly enter the macro from there.

The reason we use the palm after the second casting and not from the start is because of arcane's potential, as well as the fact that it gives you an additional 30% chance to be crit. Therefore, you should give it with a couple stacks, you know, higher debuff stacks, to ensure that the Arcane Blast is going to create more damage.

In this way that creates it's making more use out of a credit arcane blast  WoTLK Classic Gold using a couple stacks debuff stacks rather than non-debuff stacks and also a couple of stacks or a couple of passes to activate the ICD trinkets. You'll then be getting CDs In addition to that, you're getting 30% chance of crit bonus.
