So I've been using Josh's sliders for so long now I kinda have a feel for what a lot of this stuff does. But first things first. Do what ever you feel like you need to do to enjoy the game. With that the answer to your question is no plain and simple. You seem to want to keep switching things up here and I will tell you it just won't work well. You need to decide now if you want outstanding gameplay or a half assed autosub system. You can't have both. Fatigue works well as is just not autosubs in a realistic manner. But then again they never have worked in a realistic matter so there is that. Anyways it's really up to you. But if you want the gameplay with subs you have to manually set them up in formation subs and package subs. I can tell you 100% Josh would tell you that messing with what you are asking would break his set. But again it's whatever makes you happy at the end of the day.
