Last time I checked pirates were known for plundering and attacking, not defendingwhat is new to boost for attacking army ?
I have plenty of them in my inventory
and a building already produce fragments of it (Golden Orrery)
we need attack boost for defending army
the attack boost for attacking army item should be changed to attack boost for defending army item
the defense boost for attacking army item is new. no need to change that
Pirates ARE the attacking army, so it is just fitting for the boosts to be exclusive for attacking army in this event
