I mean you have a knockdown/daze/stun based on crits, which is pretty sketchy, moreso by how ambiguous the tooltip is in regards to its proc rate. Sometimes never, sometimes I've knocked players down over three times in a row...but this is indeed what I use by default if only for the fact it has no CD.
You have a brief face cone aoe blind on a 1 min CD that breaks on damage, which is really against the fast and furious nature of Frost so what's the point you know...
And lastly, you have this garbage stun that is completely random based on circumstances. It's made easier if you take the Remorseless talent...but who is gonna do that.
You know, Blood DKs and Unholy DKs both share Aphyx so why can't Frost have it? What is all this shit? Not QQ, I'm just being serious here.
