On the patch notes, it says:

The effect of this ability has been changed from "Reduces ability recast time for a party member or self by 20% for 20 seconds" to "Increases the critical hit rate for a party member or self by 10% for 20 seconds."

I think that's what he's referring to. Still unknown if this holds true for all of the cards.
