I dont find the new call to arms to be worth it no matter the amount of stacks, if ship has 18 stacks on it I know it will be lost, and its easier to recrew after the ship is scuttled. I rather keep the guns rolling and the ship functionally in the fight until the entire crew is dead, vs boarding fleets your crew count becomes your hp, and your job is to burn their through their fleet faster than they can overwhelm your forces, its dps vs dps, slowing the burn rate is pointless in 99 % of situations. Also the old call to arms gave you 1 extra crew, if you ran 5 ships that is an extra 5 hp of crew, without penality to your ship, so you could recrew, add a crew memeber at be at 2 strength, which was more solid, than what it is now. I feel it needs a tweak, putting the ship into call to arms is a cool idea, but needs to be more reason for it. Also I personally dont see a reason why we cannot recrew using boarding, imo if your close enough to recrew with a teleporter you should be able to swap for the boarding recrew, but that is a different discussion.
