New Sinclair ult issues Feb12.

[CommissarTyr]

Most Ultimates with a duration no longer start their cooldown until the whole effect is expired, extending the timer. For these duration abilities, Sinclair can use refresher to cast the ability a second time since it isn't forgotten until it expires.
Billy, Infernus, Viscous, Venator, Warden ultimates prevent usage of Sinclair's abilities except Assistant swapping.

Can you explain further about the duration ultimates, cooldown, and refresher interaction?

A specific ability along with perceived behavior and expected behavior would be helpful, thanks!

1st Example. Doorman's Ultimate no longer disappears until the first target it is used on escapes. This time allows for using refresher to cast it again on a second target.

2nd Example. Warden's Ultimate locks out usage of Vexing Bolt, deploying assistant and Rabbit Hex.

For cooldown times, Audience Participation only starts when the ultimate fully ends so instead of a cooldown that is 40% of the skill, the cooldown is effectively 40% plus the total duration.
