You know? A full rework. Your Frostbolts and Flurry would give your enemy a stackable debuff [up to 5]. Progressively as it stacks, the movement is slowed, the frost damage is increased, and at 5 stacks the target is fully frozen for 4s and you are able to launch your icicles at its maximum potential, however once you use your icicles the debuff is gone(Talents can adjust this many ways. Ex. A talent could make it so iciciles doesnt consume debuff or resets it to 3 stacks].
