Everything in CWK has ridiculously slow KB times because of what Nexon did.
Instead of the normal method:
1 KB frame, lasts 60ms
They have
2 KB frames (first is standing, second is "flinch"), each last 600ms
So it takes 20 times as long to recover as normal monsters. During this entire time it is impossible to knockback them (and in cases where the Flinch animation is missing a hitbox, impossible to damage them for half the time).
Guardians are not missing a hitbox during flinch, you can still attack them :x
