Using the skill "Enochian" while still under the effect of the Enochian buff will not reset the timer back to 30 seconds.
Because of this, we are forced to wait until the buff timer has run out before reapplying it, delaying our other actions and lowering our dps output.

Edit: Missunderstood.

But it's hard to say if this is a bug. However it's better to use Blizzard IV instead.
