I prefer it to remain. It would be boring if everything would be easy.
Not to mention, it wouldn't make sense that a base needs power to produce oxygen if it doesn't take energy.
The fact that all energy providers can hold a charge annoys me. It would be better (in my opinion) that we have to build batteries linked to the base to store energy for during the night or…
It is kinda hard for me to pick an option.
Usually I have one main base in the shallows that is pretty large.
But I also always build small bases all over the place which are a foundation, corridor and door.
