Except that they aren’t addressing the spec is punished when both of their procs are active. You cannot avoid having Winter’s Chill debuff on an enemy when you also have FoF procs at the same time. So unless they address that, we are still “eating procs” because it is literally unavoidable. And that’s the bigger problem.
Frost Mage abilities don’t have synergy with each other unlike virtually all other classes.
The buff is a half-assed attempt to placate us. It’s not enough, and we need to keep pressing for Blizzard to actually examine the spec rather than adjust a sliding scale.
