That's incorrect. For reference:

THREE BEASTS MADE OF FEAR: The Pack can use Blades/Claws/Fangs. Give The Pack a close combat action and make up to three close combat attacks as free actions, and if you use Blades/Claws/Fangs during this action, decrease the d6 roll by 2 (minimum 1).

The power is activated via a close combat action. BCF requires a close combat action. Nothing has changed. The Pack functions as normal
