Patch 4.3.2 has dropped, and for mages, the only item in the patch notes is a 6% damage nerf to Fireball and Pyroblast, ostensibly to bring fire mages back in line with arcane mages for top prize in the What Spec Will My Raid Leader Expect Me to be Raiding With This Week Sweepstakes. For good or ill, every patch brings changes like this, as the spec balance carousel continues its eternal round.
That's been mage history, in a nutshell -- fire and arcane take turns pushing each other from the top of the PvE heap, and frost just shakes its head and queues for an Arena match. It's like a giant teeter-totter, with fire damage stacked on one end and arcane damage stacked on another. Blizzard goes back and forth between the ends, adding just a bit more of each type of damage or taking some away in an attempt to get the thing perfectly balanced, but try as it may, one end or the other is always sticking up in the air.
The number crunchers crunch the numbers after every damage pass and crown one spec king ... until the next pass, when the cycle repeats. And frost mages just watch and wonder when it will be their turn to go raiding.
