hmm well ideal rotation should probably be as follows; T3 (on pull) > F3 > F1 (using F3 on firestarter procs *Stopping cast for procs as well* as well as T3 for thundercloud procs again stopping cast) > 500~mp > B3 > T2 (YES THUNDER 2) > F3 > rinse repeat. Opener you should throw raging strikes in before F3, swiftcast is ideally used after you cast B3 in above rotation to instant cast T3 giving you a few extra seconds on your thunder dot allowing for possible extra proc but either way an increase to dps.
