at this point in my rotation, with one 30% haste buff up (hero or the meta gem), my tooltip value for flame shock is showing about 350k total damage from flame shock, if i get a second proc on my meta gem and we heroed on the pull, it's even higher because i get another 5 ticks of flame shock. this is a pretty ridiculous damage per cast for an instant cast spell. certainly higher than fulmination even with 7 stacks. you do have to factor in the lost damage on the initial flame shock, which i will try to figure out later today when i have more time, but i would put it somewhere between 30 and 50k damage you are losing, plus you can factor in additional ticks for surge procs you will gain from reapplying your flame shock if you have any other haste buffs than when you first cast it.
either way i am seeing it, flame shock with ridiculously high haste values which can certainly be had on boss pulls is probably more effective than even a 7 stack fulmination
EDIT: i am also going to look closer at fulmination with 7 stacks here. obviously no benefit from haste buffs, but with all int procs up and running and a prepot, my crit value is going to be somewhere close to 30%, 400k damage from a 7 stack fulmination+earth shock would be easily attainable, although 1 in 3 crits isn't a really spectacular crit chance, and it's rare to have a 7 stack pre pull when working on progression bosses
