In-game description of Riposte:
Blocking just as an enemy attack is about to hit causes your next melee attack to be a guaranteed critical hit.
There’s no information about duration of this talent in description.
When this talent is triggered, if player doesn’t attack within 2 secs, there’s no guaranteed critical hit of next melee attack. So, is it intended that WHC Riposte only works within 2 secs after being triggered?
