Trauma,
I've only played Destro CR in LFR so I do not have that much experience with it and hopefully I am not giving any bad advice.
From memory your weapon proc is 500 mastery whilst your ring is roughly 675 intellect and your GSR 2300 crit (or there abouts) so quite a difference. However, saying this your weapon will proc probably about double the times of the other two so less waiting if you need to get a DS in soon.
With your tier 2 set you will get random ember fills and hence generally you do not want to be over 3 embers or perhaps even 2.5 or this will be wasted. Before DS I will cap myself but otherwise try to stay low; it is a challenge though with how fast embers fill up. I did see several times though that you did not go into DS with even above 30 embers to dump 3 or 4 CB straight away (not entirely sure that this is the correct behaviour but seems sensible). Then sometimes during DS you were just growing embers and not dumping them. Like I said before there did seem to be a lack of CBs during DS.
Are you tracking your ring and GSR procs? As sometimes it seemed that you did not dump on them even though you had the ember bits.
You probably have a different tactic than my raid group on phase 2 then because I don't think I have ever been out of range of the boss however it would make sense then that your DoT would fall off. Saying this though you would be dotting the tank I think. At least for one Immolate and hence your overall uptime shouldn't be that affected. Are you aware of pandemic? So you can refresh DoTs a little early without losing DPS.
Other than that not sure what else to say about CR Destro due to my lack of experience with it. Generally though I think that you want to saving your Conflag until a few seconds left to the second charge for movement. Havoc ideally you should be pre-casting and I think you should then be able to get at least 5 in, maybe even more? Like I said I haven't gone Destro there so I really do not know. Once your target is in execute then without the 4 set SB away (ideally with buffs).
I hope this helped but take everything I said with a grain of salt.

Chancellor,
Currently reading your Oregorger heroic kill.
Opener weaker than it could be. Having more insane burst will tide you over a lot better. Either check out the one in the Demo guide here or
http://summonstone.com/warlock/demon...monicservitude (fantastic site with tonnes of info)
Number of DS casts for fight length good. So not including opener but 2nd DS: 6 Meta SF, 3rd DS: 2 meta SFs, 4th DS: 4 Meta SFs, 5th DS: 7 Meta SFs. DS is simply our best buff and needs to have our up most respect in order to get the most out of it. As far as I know you can't tell how many MC procs in the logs you have but on DS 3 you went in with only just over 500 fury. The rest though you went in with over 800 so good there. Just remember to have 6-8 MC procs as well when you go into DS. I know the pain of them not always proccing on ST fights but then it may be worth using your 4 set to fish for them. Not a single CW. This can be a good thing as making that decision is advanced.
So looking a little deeper your 3rd DS seemed to be during the roll phase. During those 20 seconds of DS you managed 1 HoG, a corruption, a Drain Life and your 2 meta SF casts. Such a loss in dps. During DS 4 which you entered with high fury you managed 4 meta SFs, 3 caster SFs, a Doom, 2 Corruptions and a HoG.
I estimated that Ore went into 25% just before the 4 minute mark. Previous to this you had 10 caster SF casts which could have bought you some nice meta damage. 4 of these were probably dumping MC stacks before the 25% mark (which is good) but if you think ahead a little more and realise after DS 3 you are not going to have DS 4 until execute then you had over a minute to dump stacks with your buffs rather than them being unbuffed. Though are you tracking your BMC and your ring? Your dumping happened right in between the procs unfortunately. The same happened after DS 4. It had finished though you still had excess fury as you were in caster for some it so you carried on dumping with no damage procs and a few seconds later your ring activated.
For Grimoire you could have got 4 rather than 3 in the whole fight but this is difficult sometimes to calculate if you are not sure how long the fight will last. Your casts though were at the most random times. Pets also benefit from our buffs so you want to be combining GoServ with DS. The extra doomy lasts 5 more seconds though so ideally you can set it off first before you get the damage increase. If you really struggle on this/forget him consider a macro. It would be better than having your extra pet running around unbuffed.
DoT uptimes for Ore are 70% for Corruption and 85% for Doom which is pretty low. During the roll phase he might be out or range but unlikely to be for long. Going by the graph though it seems like at different points in the fight you just forgot to refresh your DoTs. Does your UI work properly for you? You also had 17 Doom casts so I guess some of these were on the crates. Unless it will live for one tick of Doom which is just under 15 seconds then it is not worth using a target. Perhaps though the crates you did DoT lived a long time and hence ignore this and do what works for your raid. For extra dps you can send your pet just following Ore for the whole fight rather than constantly target switching if crates die really quick. Being honest I still haven't figured out how to do decent damage on the crates whatever I do.
Your HoG stacking and therefore HoG DoT damage is rather poor. HoG, caster ability, caster ability, HoG (or with more haste/BL you can probably get 3 instants in). Do not be capping HoGs or throwing out single ones.
14 Drain LIfe casts, are your healers that bad? Or do you think it helps with crate damage? Soul Link, Soul Leech and the resolve glyph make us locks pretty hard to kill.
Last but not least execute time. You got 2 DS here so good stuff. Are you aware that Doomguards do 20% more damage in execute? Hence you want to save one summon for there. You did do this and combined it with a potion so nice work. Only issue was then that DS happened 13 seconds after your potion.
Good luck Chancellor. I didn't look at your other logs but for most people their issues are the same regardless of the fight. I will try to have a look later at one of Aamix's if still wanted.
