My new rotation is: Swiftcast > Raging Strikes > F3 > F1 spam until 500 mana, using firestarter/thundercloud procs > B3 > T2/T3 depending on size of your mana pool > repeat from F3
T2 vs T3 is mostly situation, normal rotation under ideal doesn't need the length of T3, so the extra cast of T3 is worse. Ideal isn't always available when dodging etc so just using T3 is fine.
