Why not , and simply, to introduce- FINALLY!- fatigue for ships crews, finally, finally!
I've done so for sub crews. +1 fatigue per day in any TF. I just had no idea how fast to decrease fatigue for disbanded subs. I'm not sure if fatigue does make sense for surface ships, though. They seem to be less long on mission. And less uncomfortable to their crews.
Fatigue for surface ships certainly.. It has been the factor in combat operations and in combat. Prime Example: Battle of Savo Island - after three days on constant high alert allied crews were put down to relax during the night. The results are pretty well known ...
But it would have to be put in a bit different way (subs too maybe): When patrolling in close proximity to home base or without enemy air/surface/underwater presence the fatigue should raise only slowly. But when on actual operations, high alert, it should be climbing rapidly. Consider 3 days high alert to be maximum to endure, then at least 1-2 days of rest should be necessary.
Also while the game allows carriers to launch numerous full strikes ( about 8 days worth for Essex class / full plane load / once a day) before sorties run out the common practice was to have 2-3 days on station with 1-2 at refueling/replenishment out of combat. And even then the parts of TF58 put to ports like Ulithi for 3-5 days to get some rest, repairs and resupply so that of the TF58.1-4 usually 2-3 groups were in "front" while 1-2 were refueling/at base).
So this would be pretty hard to code...
Also a boring sub patrol without encountering enemy ship/plane for 2 months wouldn't require much rest. Compare it with an action packed patrol with sub to be hunted by several planes daily, fight a convoy battle, evade 2-3 ASW groups and encounter a portion of carrier fleet! The guys would sure be pretty beat up after that!
