Convert and raging strikes, nope i would not do that or are you using it after your fire3? If that is the case then that is fine.
Thunder would not be good for a aoe rotation but if you want thunder, you may do so after Ice3, Ice 3> Thunder 2
Many start off with Fire 3 for rotations but myself i usually always start with Ice 3 since then the Fire 3 cast will be sped up.
Unless using swiftcast for Fire 3 the time it takes to cast Ice 3 and Fire 3 is about the same so why not add the little bit of extra damage and then go all off in Astral Fire.
Also when thunder or Fire procs, do not stop a rotation to use them as this is a loss of dps, you can say after fire 1 it procs, you can cast another fire 1 and then use Firestarter
