Knockup and knockback are the only Pure CC, can't be cleansed can't be reduced. They disable for said amount of time 100% of the times they are hit. Then other forms of hard CC would be, stun and fear, complete loss of control and effective against everyone.

Silence only affects casters, blind only affects auto attackers, slows don't disable. Whoever counts Silence as hard cc is a silly billy :3
