A few months ago I changed my frost spec mage to arcane, pretty much just kicking off Icy Veins, then nuking Arcane Blast continuously. Her damage went up 40% or more.

I keep reading about how Fire is the "ultimate damage dealer," so I changed her to fire last night and hit heroic Mechanar. Wow, how disappointing. Her damage went back
down between 10-30%.

Her gear isn't great by any means, only 718 +spell damage without buffs, but I can't believe how bad it was.

My (latest) macro does this:

/use 13
/use 14
/cast Icy Veins
/target [target=focustarget,harm]
/castsequence reset=target [target=focustarget,harm] Scorch, Scorch, Fireball, Scorch, Scorch, Fireball, Fireball, Fireball, Fireball

I had tried five Scorches up front to stack the bonus, but the damage was actually worse (not to mention losing out on the stuns from the fireballs, which are worth something in heroics).

I've looked at the wiki and other threads, but there isn't much about optimizing a Fire Mage's damage (without having Tier 4+ gear).

Any suggestions on how to improve the damage output? I like the extended range, stunning ability, and not running out of mana mid-fight that arcane had problems with...

Here's a link to the toon, if it matters:
