Concerns:

If you raging strikes on your first fire cycle, you WILL pull aggro if you get any procs at all.

Why no double flare with a fire 1 and a potential fire-starter proc?

Why no ether flares?

Why not blizz 1 instead of scathe?

Still unconvinced that transpose into firestarter is better than breaking/holding blizz 3. You lose a quick fire 1 cast.
