How very pedantic.
Stuns take control away from the player for longer than death does. Death may take you out of the action longer, but you're back in control of your character the moment you hit the respawn button.
And I'm not talking about removing all CCs, just stuns. Roots, knockbacks, pulls and slows are fine, since the affected player can still do something. If you're stunned and your CC break in on cooldown, then you're SOL.
Finally, how incapacitating spells in old school RPGS work do not apply to online PVP.
