Thanks, I'll re-work my rotation with this in. It does sound like it might help a bit!If this is your worry, use SHARPCAST (I typo'd I'm sorry) -> fire I before starting a fire IV rotation. Without movement, you have time for 3 fire IVs and then you can use your fire starter proc to refresh AF with no down time. Obviously, this can only be done once a minute but it's better than wasting swift and it'll make you feel less stressed while learning the timing.
I usually went:
Quelling Strikes > Sharpcast > Ley Lines > Fire I > Enochian > Raging Strikes > Fire III [Proc] > Fire IV > Fire IV > Fire I > Fire IV > Fire IV > Fire I > Convert > Fire IV > Blizzard III > Thunder I/II > Blizzard IV > Fire III > Fire IV > Fire IV > Fire I > Fire IV > Fire IV > Blizzard III > Blizzard IV > Fire III
From here, I continue with Fire IV until Enochian drops, in which I reapply [thanks to the ability being available again] when I enter the next Umbral Ice phase. Next Enochian rotation, I won't have Raging Strikes or Ley Lines available, so that set of rotations is more simplified.
I'm still tweaking my rotation a bit, and of course this is my "ideal" rotation, but mechanics can mess with it a bit.
