From the patch notes:
1.Successful use of a CC tactic starts the corresponding timer.
2.Using a CC tactic while its cooldown timer is still active will render its effect duration halved. Likewise, using a CC tactic when its effect duration is already halved will render it halved yet again (1/4 of the initial duration).
3.A CC tactic whose effect duration is quartered will be completely resisted by the target the next time it is used. This resistance will remain in place until the cooldown timer falls to zero.
Players are returned to step 1 above when the cooldown timer falls to zero.
* Target resistance remains unchanged prior to step 3.
What, exactly, does the '*' mean? Once the appropraite cooldown occurs, does this revert to #1, or if you used the CC ability until some lesser effect during cooldown, when the timer is back up, is it at some lesser duration?
