Another tip.... ALWAYS use the last firestarter proc you get before going into Bliz III. I heard some people save it to get back into AF3 faster. That is horrible. Why?

For me Fire III in AF3 can hit for upwards of 1900. In addition, the cast time of a hardcast fire III in UI3 is faster then the GCD. If you save the proc for after a bliz III and thunder.. you will lower your dps because the fire III wont hit near as hard and you still have to wait for the GCD
People mostly save it because to use it you have to pause after the last cast and wait until your Fire 1 actually lands on target and applies Firestarter on you (or may not) so you will be losing extra ~1 second every Blizzard III just to understand if Firestarter procs. So generally you will just chaincast Blizzard III after the last Fire 1 and you will understand that Firestarter procced in the middle of the cast. So I am not sure if it is worth it to make that pause.
