Is there any formation (or just about anything!) that can make submarines less vulnerable to ASW attacks? E-4H is slowly eating at my (and my shipgirls') sanity with constant submarine taihas. Not even once reach the boss. I've tried practically everything aside of touching formation: drugging submarines with superfluous turbines and boilers, preboss support expedition, and even dedicating LBAS to preboss nodes. Thank you in advance.
