In the current state of the game I would rather see most CC only reducing the initiative and dodge of the character for the current turn instead of making them completely skip their turn.
If all stunned would simply act last and anyone attacking them has his max chance to hit, this would be a good enough advantage I think for the amount of CC currently in the game.
And of course this will also help having more diversity in CC. Right now most CC just make you skip your turn (Frozen = Knockback = Stun, ... etc with only minor resistance variations).
