Rotation/dps

Would like to know a good spec/rotation for dps for 5 mans and heroics at 85.
LB, MI, Fire Orb, Fireball (weave scorch with fireballs if you are worried about mana, but fireball will ALWAYS be over scorch if you have the mana for it)

If you need to move around, ALWAYS cast something, scorch being the used mostly, or LB if you need to refresh that, fireblast IF you have dots you need to spread to other mobs and it's proc'ed.

Pyroblast! should be used ANYTIME it's proc'ed.

It's best to use Combustion whenever you have all the dots on the boss (Combustion Helper is a great add-on for this, personally I found most of my time waiting for Pyroblast!).

It's hard to find a specific rotation for fire mages because thigns are based off of procs and situations. The best thing to remember is ALWAYS keep your dots up, use Pyroblast! anytime it's up, ALWAYS keep casting NO MATTER WHAT. Scorch is one of the most amazing spells for fire mages now, you can cast while running AND while falling or being blasted away by something, and it's totally FREE! Keep up any cooldowns - MI has a bit of a timer but Fire Orb is only 1 minute, so you can use it multiple times in certain fights.

I've also found that in certain fights when a crap load of mobs come, throw a blast wave in the middle. This will throw an instant flame strike and significatly more damage with one single instant cast.
