Patch 5.1 Changes:
Recently the Fire spec has been slapped with a huge damage nerf, our Combustion now does 50% less damage and Critical Mass is only a 1.25x multiplier instead of 1.5x. While this does not change the gameplay of Fire at all, our DPS has taken a huge hit and Fire is no longer the dominant Mage spec, I will be updating this guide soon covering both Frost and Arcane specs, so be sure to check back every now and then.
Combustion - No longer takes Mage Bombs or Pyroblast into account and is solely 50% of your current Ignite.
Critical Mass - Now multiplies our crit chance with main spells by 1.25x.
