At 40% CDR Q goes down to a 3.6 second cooldown. And that's wihtout his passive lowering it even further.

Cast Q, Cast E, enemy is stunned for 1 second, Q now has a cooldown of 1.6 seconds, cast Q again 0.6 seconds after the first stun has worn off, cast W, enemy is stunned for 1 second, Q again has a cooldown of 1.6 seconds, enemy is snared for a further 1 second after the stun has worn off, cast Q at will,...... etc. etc. etc.

The enemy has a total 'able to do anything' period of 0.6 seconds per 5 seconds.
