Im sure most have you have ran across it already, but if you havent...the new PTR build brought in a new new Mastery for Frost in the form of Icicles.
Who knows how it will play out...but it seems like it will help with the consistency of Frost Mage damage in both PvE and PvP, and rely less heavily on blowing all of your procs at once..not to mention it seems like it will be pretty fun. Who knows how much damage the Icicles will do.
Thoughts? Im personally excited
