PvE frost and FF

I'm /really/ confused about this. I've read Elitist Jerks and several threads here, but it's still not coming together for me.



So, when FF procs [and BF/DF are both down]



Do you you cast:

FB -> FB+IL



or

IL -> IL?

or something else?





Likewise, when DF is up, do you cast:

FB -> FB+DF

or

DF -> IL?
Taken from Elitist Jerks:







Perhaps the biggest news for frost in Cata is that there is an actual rotation to use in raiding and that there are enough levers to adjust that it is to be expected that frost damage should be raid-worthy without being overpowered in pvp. This is a huge change for frost. The current theorycrafted rotation can be expressed as a priority list. You are monitoring various procs and cooldowns and make your decisions based on the following rules.







1.Frostfire Orb, if cooldown is up.



2.Deep Freeze, if cooldown is up and Fingers of Frost is active.



3.Frostfire Bolt, if Brain Freeze is active and Fingers of Frost is active.



4.Ice Lance if Finger of Frost is active.



5.Freeze, if cooldown is up, Deep Freeze cooldown is up, and Finger of Frost is not active.



6.Frostbolt.

so you only want to use frost bolt when FoF is not up, With frost fire orb as a higher priority if its not on CD. Only use pet freeze when deep dreeze is off CD,
You know, I've read that probably four times. For whatever reason I kept skipping this line:

so you only want to use frost bolt when FoF is not up

Thank you.
