For AOE You said "
- Fire III
- Fire II
- Flare
- Transpose
... rince and repeat"
You will get off 1-2 x BlizardII's right after transpose before your back up to full MP to start the switch into FireIII>Astral Fire depending on when the transpose is registered.
Or you could just sit there and do nothing while MP refreshes, which as I understand is what you are saying?
On ST, even if you don't have swift cast or convert up, why stop @ 1000 MP? that is still 2x Fire 1's + a Blizard III.
Even though I did actually say Convert/swiftcast/flare - so I guess you're agreeing with me there but want to sound like you knew that but didn't include it in the OP?
Like I said, I don't think your rotations actually represent efficient MP usage.
EDIT: Quelling strikes is useful for when you have novice tanks. But if the tank has any clue what he's doing, you won't need this.
