Enhanced Shake (Aka Vibration) actually works against Kung Lao's spin.
It's abilities seem pretty random.
Against some characters it beats all, even non projectile specials, some need to enhance specials to beat enhanced Shake etc.
Although enhanced Shake works consistent, there is no real rule of thumb to which specials it applies, so i strongly advise you to study this awesome list of moves that beat enhanced Shake that Finaeous made:

It's really helpful!!!
By the way i don't think it beats all projectiles for exaple it doesn't work against Smoke's own Smoke Bomb.
And enhance shadows from Noob beat it too.
And yes it is beast, makes people loath using fireballs against you.
And enhanced Shake snuffs out all jump in punches and jump kicks.
