I was mainly debating Deep Freeze being termed as a controlled stun, a conditional stun is much better and I fully accept that.Originally Posted by AetherMcLoud
However, on the second part I have quoted, I just wanted to show that it is not always possible to cast Deep Freeze. You cannot control Fingers of Frost, it is a random proc, and while you can control Frost Nova, it requires a GCD in order to freeze them before you can stun them.
You know as well as I do that a GCD is plenty of time to hit shapeshift/dispel/blessing of freedom/cloak of shadows/escape artist/anti-magic shell/blink, all of which would break the Frost Nova before you can stun them (except AMS which would just stop the stun from being applied, as would IBF).
And against good players, it happens a lot more than you would think.
