It is true that CoD has only slightly lower DPS than CoA, and for total DPS over time, considering its lower damage/cast, it yields slightly larger theoretical values. For example, if i use 120sec cycle, i get around 99k dmg from afflic using CoD and 97k if using CoA.
But there are few reasons why in reality, and even theoretically, CoA should still yield more damage:
- CoD deliver full damage only if boss mob dies after full minute or close. In one minute period CoD deliver about 1k more damage that CoA (if we consider damage added casting other spell). That 1k damage is something that CoA will produce in about 10sec, so if CoA tick 10sec longer, it result in more damage. It accumulate over time, so for long fights it has less negative effect on CoD if last CoD was not used, but for fights under 4min, CoD would win in about 25% cases (if fight end randomly with equal distribution)
- CoD is still musch more prone to being removed from buff list. 40 slots are not infinite
- CoD potentially has more risk of getting mog aggro on lock

Also am I correct in reading that your accounting of Improved shadowbolt is to increase shadowbolt damage by 1.6%??, even a conservative probabilistic model would show that a poorly geared Destruction lock is at least gaining 5% more shadow damage to corruption/cod/coa/shadow bolts in his cycle yet the multiplier isn't included in any of the dot calculations.
you are correct here, I included imp SB effect on SB itself, not on DoTs. And on SB, i used more conservative value, since only way to get full 5% on SB, is if you cast only SB once effect is up, which would ignore need to LT/DP if low on mana, need to recast DoTs (which potentially can lower DPS) etc.
But I will add more accurate effect on both SB and DoTs, which will not be 5% fixed, but will be linked to number of SBs actually used and actual crit chance in build.
I do not expect that it will change relation in damage between builds, since most lvl 70 builds have imp. SB ;p

I haven't been able to test it yet, but I was under the Impression that S&F was additive to the spell damage to damage ratio. ie. 3/3.5 = .857 then getting shadow&flame adds .2 to this result changing the ratio to 1.057 spell damage to damage for shadowbolt. I'll test this next time i'm able to though.
I expected that S&F adds to same thing to which Demonic Knowledge adds, ie to +dmg ( to bonus damage from items), rather than to *dmg% (to spell cast time modifier). If that would be different, I believe same would hold for Empowered Corruption, and would indeed change numbers a bit.
