The goal of this addon is to allow easy optimizing of the mage talent Combustion. It tracks all relevant Dots on your target, your cooldown of Combustion so you'll be able to use the talent with maximum effectiveness.

To summarize the new talent : it will add a new Dot on effect on your target which will be equal to the sum of Ignite and Pyroblast Dots.

With this addon, you'll know if one of your Dot is missing.

CombustionHelper is composed of the main addon and 2 bundled other addons : CauterizeCooldown and MageBombTracker. Here is their main features :

CombustionHelper main addon:

Automatic switch depending if combustion is in your spellbook or not.
Autohide out of combat is off by default, use config panel to configure it. You can choose between no autohide, autohide out of combat or autohide when combustion is on cd.
Reset variables option because i know some of you like to bug the thing by switching options while in combat/autohide is running and stuff. If you bug it, just reset and log off so you start with a clean state.
Option to hide all config messages in chat.
Dot tick damage report mode. This is not the expected combustion damage report because of the complexity of ignite, rather an information about how much damage the last tick did so you know if it's powerful enough.
Pyroblast/Hot Streak report mode which will warn you when wasted an Hot Streak proc will letting it be refreshed before getting used and at end of combat will report number of refreshed Hot Streak.
Timer for Combustion Dot on target.
Flamestrike tracker supporting regular flamestrike.
Tooltips for option panel settings, no more obscure settings.
Ignite munching report, so you know how much damage you lost because of buggy mechanics.
Graphical options so you can make it the way you want.

----------

Changes from 2.xx versions ?

No more crit debuff tracking, it's gone for mages.
No more support for FrostFire Bolt, useless for Combustion and i doubt anyone used it.
No more Impact support, new inferno blast replaced aura procs.

Use Interface Panel -> Addons for full config or /combustionhelper for bringing up directly the option panel.
As always, report me bugs and requests.

Donation is totally optional but all funds will be used to buy chocolate for my wife so she'll be a bit less mad at me spending so much time coding.
