Culverin moves slower than bb, cul needs to turn to get back and get shoot, cul needs 3+ to counter 1.
Cul is the only siege to counter bb for France.
Good lord!
Does Relics realize it takes time to turn around back? how could bb get 11 range and counts from the front instead middle like Trebuchet. I always found my Trebuchet range less than bb somtimes when it search a bad place to attack.
