Yeah, I agree. I maintained the MMO-C sticky for Fire and discontinued it for the same reasoning. People just aren't as interested in the spec anymore.

So, from how combustion behaves in general, the primary thing should be to get as big an ignite as possible before hitting combustion. From what I saw in the logs I've looked at (I haven't had a chance to do alys on my mage) combustion is probably not directly affected by burnout.

Assuming you actually have 100% crit on pyroblast (and not just very close to it), this means you want to spam pyroblast until your ignite ticks as large as possible and then hit combustion. The contribution to combustion from living bomb and the pyro dot should be small enough that it doesn't really matter if you have DMC:V/PT/other spellpower procs up for the combustion cast, although you'd want them for the ignite stacking.

For total damage done by combustion, hitting impact to gain pyromaniac before hitting combustion will give you about 10% more total damage on combustion, which is obviously good.

If you have a log for those ticks, I can look and see why you had larger ticks one phase or another.

More recently I've been using the macro for the ground phase of alysrazor:

My theory is that this will prevent ignite munching from multiple pyroblasts hitting the boss per second. Allowing for larger ignite, combustion, etc.

Can anyone comment on this practice? Is it incorrect to prioritize my DoT damage over raw spell damage?

Well, you won't lose any raw spell damage using that macro except possibly a single pyroblast at the end of burnout or at the end of razor. (1s GCD vs <1s cast with 1s GCD is the same thing) Whether or not its any use I'm less sure about.

While the section of the fight before the 24 stacks is short your still gonna lose a lot of damage by doing this won't you?

Yes. Especially with 4set T12 the amount of lost hot streaks will be sizeable. Basically you can get lucky and avoid munching altogether with a simple /cancelaura macro, or you can spec out of HS altogether, lose some damage (I haven't done any numbers but it seems sizeable, of course wildly depending on how many hoops you actually hit since you can spend most of the third flying-cycle at 24 stacks or more) and always get a huge combustion.

I really don't know if there is a way to avoid munching while keeping HS in your spec, but it's a matter of luck with the cancelaura macro, and it certainly is an improvement over just spamming Pyroblast.

I've been looking for a knowledgeable mage for a little while now that knows Ignite's mechanics inside out. I've created an info-graphic that I want to submit to the fan art section and be linked as a resource on fire mage guides to clearly explain how Ignite works.

Essentially I'm not sure if I have my facts correct and just wanted someone who knows to confirm I'm not spreading miss-information before I submit it.

I've uploaded it here:

If anyone can confirm this is how it works it would be great, or if they could explain where I need to make adjustments that would be just as awesome.

Thanks Talchas, I've made a small adjustment and submitted it to the fan art section.
Here's the link: http://dewfish.com/uploads/ignitesml_new.gif
I didn't want to include too much detail about munching and the focus to remain on how the DoT works, however it deserved a mention, perhaps the next piece will a visual breakdown of the what, why, when and how of Ignite munching

So tier 13 and Fire spec...I assume damaging spells include ticks from LB/Pyroblast(!) DoT/Ignite. Which means we'll be rocking hard with the haste bonus all the time...80 second Combustion will be nice, very nice.

If they buff us somehow for 4.3 (I hope for 4.3, because I have a feeling they're just gonna rework the class in the next expansion and not help it for 4.3)...Then we should be pretty good. 80 second Combustion will be nice, very nice.

Just a reminder, given that Patch 4.3 PTR will go up soon and we might be in for some Fire changes.

If someone is up for the task of remaking and maintaining a new Fire thread ("Updated for Patch 4.3") - please feel free to step forward. Contacting an EJ mod first to express your intention would be a good start, as they'll likely want to lock this old thread shortler thereafter. Feel free to use any of the text/tables/code from the OP of this thread, if they'll be useful to any newly created one.

It looks like Fire is getting some big buffs on the PTR.
