Crew on Mutsu

For a while I’ve been wondering about the placement of the forward most crew compartment on IJN Mustu and the fact thats its completely unarmored. When I first got her it was baffled how fast my crew disintegrated and it only gets worse when angled forward. I’ve taken upon reverse angling, something I find works quite well with all IJN capitals oddly enough except the Kongos, but then turret 3 gets annihilated with that shell room. From a quick look at other nations capitals ships I can’t find any others that have a whole crew compartment completely exposed allowing destroyers, heck PT boats, to kill Mustu easily. Curious what others think about this as well. Thank you.

in Barham, the crew is also housed in an unarmored compartment
