Fire Mage spell damage disparity

First post here. Maybe someone can help me understand this. I’ve been leveling my fire mage and was having fun up until hitting 70 and suddenly slamming into a damage wall. Figured it was me being bad or having bad item level or whatever.

But then I swapped over to my same level Fury warrior.

The damage disparity between the two is confusing me.

(Mage)
Intellect: 8K
Item Level: 359
Fireball: 19K
Fire Blast: 12K
Pyroblast: 23K

(Warrior)
Strength: 8k
Item Level: 349
Bloodthirst: 55K
Raging Blow: 45K
Rampage: 71K

The numbers pretty much speak for themselves. 12k for a fireblast? 23k for a pyro? Combustion isn’t saving those puny numbers. And then you have my warrior with 10 less item level and the same primary stat and they’re doing 3x my damage without even accounting for stuff like Enrage and Raging Blow boosting Rampage even more.

Can anyone tell me what is going on here?

all your damage is loaded in combustion, you will do tank damage, nay healer damage outside of combustion.

your only goal is to use combustion as efficiently as possible in order to reduce the cool down of your combustion while your in combustion in order to go back into combustion so that you may do good damage.

The amount of Pyroblasts and Fire Blasts cast as well as Ignite is what you’re missing in comparison.

It’s worth noting a good chunk of Fire’s damage comes from Ignite, which your spells passively apply.

Also, classes are balanced around current end game content, so at lower levels classes often experience pretty drastic performance disparities. This has been the case in the game for a long, long time now. (Also your Mage has relatively low intellect, as casters have bigger main stat numbers than melee do)

Right now Fire doesn’t really shine until you get tier set and a lot of haste and are able to maintain a high uptime on Combustion. Even then Fire’s strength is AoE (spreading Ignite), as its single target DPS is nothing special.

Warriors (and all strength/Agi classes in general) use Attack Power, not strength or Agi as their primary stat multiplier.

For Int classes, Spell power = Intellect
For Strength/Agi classes, Attack power =/= Strength/Agi

This is because your weapon gives you a “hidden” amount of Attack Power that is in direct proportion to iLvl (and damage per second of the weapon)
