Yeah, that bothered me too. But maybe Old One didn’t know how long it would take to activate the Countermeasure.
Or maybe when the Blight fleet reaches the Countermeasure it can undo it and revive the Blight, so by delaying the fleet arrival they make it possible for the Tines to build up fleets of their own and defend the Countermeasure?
