With all that in mind, my proposed changes are this:
-Immolate generates one ember per tick and two embers per crit tick. This would preserve the value of haste and offset the ember loss from RoF. Avg embers gained in sims would be 236 from ticks + 120 from tick crits = 356 compared to 120 from immolate + 113 from RoF = 233. Result = avg of 120 extra embers per sim.
Current numbers are right here

-Implement Glyph of Chaotic Haste; "Decreases cast time, damage, and ember cost of Chaos Bolt by 50% but it is no longer affected by backdraft." This should help with destro in PvP while not being ideal in PvE due to it still taking three charges of Havoc. The number is also not set in place, I was simply trying to come up with a baseline number.
-RoF generates 80% less embers when used against a single target. This will ensure that RoF will never be a part of single target rotation again.
-Backdraft now also increases the damage of Incinerate by 20%. This would give incinerate some of the oomph! it really needs (it deals on avg 20k less than shadow bolt).
Now my reasoning. RoF will in all likelihood still be included in the single target rotation, simply because it has a higher DPET than incinerate. My RoF change will make sure that won't happen again. With RoF being out of the picture completely, we would lose around 9% of our DPS from RoF damage and the embers that come with it. The immolate buff would give us all of those embers back plus we'd be gaining a rather large amount of extras. It would also preserve the value of haste and even crit. The backdraft buff would ensure that Incinerate gets some kick to it and it would be a decent buff overall to get us in line with the other specs. Lastly, the CB glyph would let us get CBs off in PvP without making it OP. The damage nerf to CB against players might have to be reverted, but I'm not sure.
