for instance if you know an enemy or pack will die very shortly after but you run the risk of astral fire dissipating before you could transpose again to make sure you have full mp before next pull, you wouldn't want to use transpose in my opinion.

Transpose > Fire 3 Proc > Fire 1 > blizzard 3. That will solve your MP worries. If you won't have time for a Blizzard 3, then replace the Fire 1 following the proc with a Blizzard 3. Won't have time? Then you'll be at max MP anyways lol
I've never had an instance in which transposing into a firestarter was a negative.
