I decided to discontinue this addon, since there are others who do the job much better.
LureCombustion is a DoT timer that also displays the damage of the last tick for each DoT. This way, it should help players maintain DoTs, and to decide when to use Combustion. You get 4 bars (Ignite, Living Bomb, Pyroblast and Frostfire Bolt).
The addon is only enabled for mages, and hides itself when you're not fire specced.
