There is enough energy in P2Pah WoTLK
Based on the speed of your attack, you could fit into missile barrage items after the first missile barrage proc, however, in case you're not able to muster enough
WoTLK Gold energy, you'll need to follow the initial missile barrage proc do six or seven arcane blasts finished by a missile barrage Proc. And the reason for that is that arcane power scales dynamically with your Arcane Missiles.
Thus, if the arcane power ends at the midpoint in your arcane missiles this is because the later part of the arcade missiles won't be benefiting from arcane power. Those missiles are going to cause less damage it doesn't snapshot. This is why you should make sure that you utilize the Arcane Missiles during the arcane power. You want to finish the arcane power by using full Arcane Missiles.
You don't want to make use of it prematurely. You don't want to be in the final couple of seconds you have Arcane Power to be restacking, your Arcane Blast debuffs. This is just a little min max tips to help you maximize your damage in the burst window. The main thing to remember is that when you burst you must ensure there is enough energy that you can use arcane blasts, and also fishing for missile barrage items.
It is not a good idea to utilize missile barrage in two or three, which isn't the best time to be doing a conservative rotation. Therefore, if you have to do anything, control management outside of the burst window , so that during the window of bursts it is possible to be spamming Arcane Blast fishing for missile barrage product, or at a minimum, climbing enough forest axe and using your missile-barrage Croc.
Additionally, the reason we employ palm after the first cast and not after the third is because , in Wrath of Lich King, you aren't able to use presence of mind and arcane power at same time. When you use palm, it puts arcane power on a 1.5 second delay. So if we use palm immediately after casting the third time in order to
buy WoTLK Classic Gold acquire the forest axe then we try and use the macro, everything in the macro will be able to go off much earlier than arcane power.
