Get HU/HS first (personally I get HS), then cast RoP followed by fireball. Just before fireball lets off, cast Combustion/on use trinkets racials whatever. Or if you're using Cinderstorm, use that and Combustion before CSt cast lands (if you do that right you will get 5 stacks of Pyretic Incantation and do some huge damage). Then it should go Pyro > FB > Pyro > FB(if off CD, if not FO then FB) > Pyro > FB > Pyro > FB/PF > Pyro > PF > Pyro ( this is probably slightly off, but pyro > fb > pyro > fb spam)
At that point RoP should be just about ending and Combustion maybe has 1 second left.
