I saw this on the target dummy last night but did not experience it during the raid. I assumed that either a frost mage or shadowbolting warlock was overwriting the debuff, but I have no proof.

But no, I was scorching last night and every scorch lasted the full duration.

Check your warlocks, the improved shadowbolt and scorches have been fighting each other pre 3.1.1.

You're saying the server detects the presence of "duplicate" debuffs on a target and drops a random one? Maybe each time a debuff is applied it drops all others that are no longer effective? Seems like a good change to free up debuff slots on bosses and such, but is something I would expect to find in patch notes.

Err no that was precisely the bug. It didn't, and should have. It seems like they corrected it and the highest debuff takes priority. If anything, I am glad about it, since it means if i cast a few scorch and warlock shadowbolts, then his shadowbolt will overwrite my scorch, which is good because if a 1% crit prevented a 5% crit from applying that would be really annoying.

However, I am unsure what happens if you have 5x scorch and shadowbolt is cast.

If you have 5x Scorch and Shadowbolt is cast, Scorch is removed. It's extremely annoying. Also, the Improved Shadow Bolt talent is not a debuff, it would appear, so it doesn't get "applied" to the mob. This is why, I think, Scorchio just counts the number of Shadow Bolts, because there is nothing like "Improved Shadow Bolt (#)" to go off of (even though the first shadow bolt applies the full 5%).

Also, you cannot overwrite the Shadow Bolt with Improved Scorch. What does this mean? It means that if your warlock stops using Shadow Bolt and the Shadow Bolt debuff is about to wear off, you cannot apply Scorch ahead of time. You have to wait till the debuff is gone and then cast Scorch.

It is removed instantly.

On a completely different note, WWS now parses bosses in Ulduar. It appears the logs are working correctly, and all the numbers match up with logs posted on wowmeteronline. I'm not sure if all bosses are parsing at the moment, but it appears that at least Deconstructor, Ignis, and Razorscale are parsing. Because of this, and because someone asked a few days ago how ignite is operating with LB glyph, I present:

Deconstructor - Ignite Damage.

Out of 1,126,918 critical damage, I lost 37,807 ignite damage, out of a total of 2,120,046 damage. Of the total damage I should have done then, the "lost" ignite damage represents 1.75% (37,807/(2,120,046+37,807)).

Now, there are many targets in this fight, so I'm not entirely certain how much of the lost ignite damage is due to the target dying before the ignite can tick. I would have to go through individual lines to figure this out. It is possible to see if the ignite damage being lost is due to this, or if it's due to ignite being overwritten, without actually knowing if the target died before the ignite finished. You can generally assume that if a tick of ignite never occurs and no other damage was applied to the target past that, it's probably because it's dead.

In the "Lost Ignite Total" column, you can see the real-time effect of ignite. Notice we start out with a loss of 610, and then it drops to 305, and then finally to 0. This is because it's 'waiting' for the ignite tick to be dealt. If it's never dealt, then the number will increase. If the ignite is lost, it will permanently settle on that new number.

Anyway, my basic analysis of this so far is that Glyph of Living Bomb does not increase or decrease (benign/extra ticks) ignite loss/gain any more than things were pre-3.1. Now, could this be different on a fight like Loatheb? Sure. But that fight is kind of biased against ignite loss to begin with, and 100% crit rate doesn't even imply that any ignite damage will be lost.

That's interesting. At the risk of beating a dead horse, how does that work?

Say Winter's Chill (5) is up on a target, and I don't have the Glyph of Improved Scorch. On my first Scorch, does my Improved Scorch (1) remove Winter's Chill (5)? Does Improved Scorch (1) fail to apply to the target at all? Does the game engine allow Improved Scorch to apply (1) (2) (3) (4) and finally (5) before finally knocking Winter's Chill (5) off the target? I find all this very odd.

No, frankly, I think it was a good thing that you could have Shadow Mastery and Imp. Scorch at the same time so even if one fell off, you'd still have the 5% crit bonus without having to restack it. This goes double for Winter's Chill, which gets a five-stack removed by a single application of Improved Scorch. It's not like there aren't precedents for having functionally identical debuffs on the target, but having only one effect count (Ebon Plague vs. Earth and Moon vs. CoE).

EDIT: Manly answered this a few posts back

I'm not saying its wonderful that shadowbolt removes scorch etc. However, it was really unclear whether scorch/shadowbolt debuff were stacking, and this is really the one thing that I have an issue with. If it was bugged and double applying crit then thats bad. Now obviously the system is really ripe for annoyance with warlocks not guaranteeing sb uptime on execute range, since both my options in that scenario flat out suck (scorch to stack back to 5 only to have it possibly overwritten along the way or not stack scorch at all).

Deconstructor parses did not work properly for me last night. If you look - Wow Web Stats it shows 20 attempts. From what I can see it's showing each phase as a separate fight. Dejawow.com worked better (but does not allow log browsing from the website that I can see) Combat Stats | DejaWoW.com

We had 10 attempts and 9 parsed correctly. Well, the 10th one parsed fine as well, except for the last 19 seconds.

WoW Meter Online - Combatlog Replay in Engrish

On our 10-man run, our first fight parsed correctly. Our last fight, the kill, did not -- it was split into 3 sections:

Wow Web Stats

However, all Razorscale and Ignis attempts and kills parsed correctly. The WWS team (however many it is) does work on things behind the scenes. So when you upload things, if it's not parsing correctly now, it may later.

I had problems tracking it also. I use NeedToKnow with a debuff, target, any player settings on it named "Shadow Mastery" but it does not list the stacks. As much of a good thing as we all thought it would be not having to scorch anymore, it was short lived. All 3 warlocks in my guild have spec'd out of ISB leaving me with scorch duty once again.

On that note, has anyone else seen our damage compared to other DPS drop off heavily? I know we are so busy doing other things (Add nuking on Ignis, spell stealing on Council, AoE on Kologarn, Breaking blocks on Hodir) all while maintaining a scorch for casters on the main nuke target.

Honestly, Improved Scorch should be changed to a one stack debuff that provides 5% crit. The justification for this is that Scorch is not included in our optimal dps rotation, it is a dps loss, and second, the talent is much deeper in the tree. I feel that is the direction Scorch should go.

Yeah scorchio really needs badly to get its tracker majorly updated. Everything is tracked wrong, from sheeps to living bombs, and everything in between.

deleted, didn't mean to

The reason I have asked these is questions is that I couldn't find anything about these bugs in the most recent patch notes (3.1 and 3.1.1) and when I ticketed a GM about it he told me that they are not aware of the problem.

It's even worse. I ran Ulduar 10 yesterday as rfost for some support (refreshment & crit) and our warlock had 3/5 ISB specced and with his 3% +crit was constantly overwriting my winterchill-stacks, resulting in a presumed 2% critloss for the casters. So if the same holds for scorch, then yes, 1 Scorch will remove a fully stacked winterchill. This can be seen as a bug, because it causes a talent to actually cause negative rdps. Maybe someone can report this on the US forums.


@Delicija
Yes, I noticed that. Just ask for reapplication. It's annoying, but not as bad as the bug mentioned above.

@Pye
The behaviour in question was the removal of FM cast on YOU if YOU switch specs (even if you are specced into FM, which is of no importance whatsoever), not the dropping on the target of your FM.

What I wanted to point out with this is that you can't have 2 FFB mages with Focus Magic up on both of them at the same time which is kind of lame since we are losing 3% crit because of this.

There are blue posts that directly address this. That was not an intended benefit of dual specs, anf as such was hotfixed.

Just tested this with a lock, 5/5 isb. He would always overwrite my Improved Scorch stacks with Shadow Mastery, but I could not overwrite his debuff, not even with Glpyh of Scorch. It seems the game sees Shadow Mastery as superior to Improved Scorch, since it is only one application instead of 5 stacks. I guess the same goes for Winter's Chill, but didn't test this today. In the past, I could overwrite Winter's Chill as long as not 5 stacks were applied. Once 5 stacks were on the target, I could not put up Improved Scorch, with our without Glyph.

On a side node, I have no problems at all tracking Shadow Mastery on targets with Power Auras.
