Just kidding. I kid because I love, guys. If the joke hits a little too close to home, though, it's because there's a very real, very prevalent, very false perception out there. It goes something like this:
Frost is for PVP. It isn't viable for raiding.
This sentiment has been around at various levels of general acceptance since patch 1.1, and even in the most enlightened corners of Azeroth, you'll still find those willing to perpetuate it. But then again, you'll also find people still willing to perpetuate things like racism and gender bias, so I guess ignorance, like a weed or a cockroach or a warlock, is remarkably resilient.
At any rate, in today's State of the Frost Mage address, you'll no doubt discover a recurring theme. That theme is this:
Frost is absolutely, positively viable.
