My single-target rotation:
Engage target > Blizzard III > Thunder III > repeat Fire; if Firestarter, Thundercloud proc then use > if MP less than/equal to 800 then Blizzard III > Thunder > goto repeat Fire
If you open with Blizzard III, then the MP cost and cast time of Fire III is not an issue, and you can start with Thunder III and get all of your MP back, so you can start repeat-casting Fire with nearly full MP.
This parses higher than building AF3 through Fire casts alone and gives the tank a bit of a threat "lead" that opening with a Swiftcast Fire III does not.
