The problem: The Freezing Band proc does not count the target as "Frozen".
How it should work: The Freezing Band proc should consider the target as "Frozen" while it is stunned. Ice Lance shall deal 3x higher damage on it and talents like Shatter shall apply.
How to reproduce: Make a mage and equip 2x Freezing Bands. Get hit by a physical attack. When the target is frozen, cast Ice Lance. The damage will not be 3x higher and the Shatter talent does not apply.
