If you have three stacks of AF and use
Transpose you go to UI 1. Less mana is returned per tick.

Using ice 1, cancels it out completely never use it in Astral fire

Using blizzard 3 will immediately switch you from 3 stacks of fire to 3 stacks of ice. Refilling your mp by the time you cast a single thunder spell. UI 3 also reduces fire sPell cast time and mp cost, so you can swifly get back into damage mode.

I really recommend you taking a few moments and actually reading your spell and trait tooltips and possibly watching a video or two on the class, you've already built some really bad habits
