It makes me wish resupply ships had its own separate classification for everything. e.g. advisor prompts for how many ships/bases to build on or off for all but resupply, same setting including resupply.
I generally ignore advisor prompts now but given you can't get auto retrofit to work without advisor prompt enabled, I dislike being told to constantly build more resupply ships when there is no setting far as I can see that governs resupply ships separately or I would tune that to zero. I can set escorts, frigates, etc to 0, but I assume resupply ships are lumped in with another bigger class like capital ships, or has it's own number setting which isn't surfaced in the UI.
Resupply ships are also the only class type ship as far as I can tell, that basically does nothing when automated. It will move back and from from time to time in the same system it was built, moving from planet to spaceport over and over, and refuel when necessary - but that's it. Escorts and frigates go escort, DD and CA go protect stuff or respond to threats, etc. Resupply ships from my aquarium watching thus far just sit there and do nothing.
Even if they went and used their vastly over to cap designed gas extractors to at least plug into some gas giant and at least start being a resupply point, that would be fairly useful. But it seems all they want to do is sit or at most if the system is attacked and it has weapons, will defend itself and/or the area it is in.
I love the role resupply ships play, very important and useful to Fleet operations if used right. But incredibly useless on auto, hard to control, and with the least support for automation vs the other class ships which at least do some basic function when left alone.
If DW-2 ever gets made, it needs to have
a) resupply ships programmed with a class role (preferably to go mine gas somewhere, anywhere, unless manually directed where and when
b) a one-click 'go back to prior deployed point and re-deploy' button so it is easy to re-deploy your resupply ships after a retrofit
c) slightly better support in AI programming for military ships to preferentially use resupply ships as fuel points vs. planets or mining stations - I find on harder levels the fuel situation can get low much faster and often minding stations are just barely able to support the private sector needs much less my fleet that comes up to tank up. Many times when my fleet is equally distant from resupply ship or mining station, a refuel order will make it go to the mining station or worse, a planet that has barely enough fuel stock to keep it's own growth going, and tank up from there - when my resupply ship has like 10x the fleet refuel needs.
You can right click and tell it to go refuel at resupply ship, but it would be nice if preferential AI order for picking closest refuel point was resupply ship, then mining station, then planet/space port.
I find most my use of resupply ships outside of the 1-2 only need to support actual front line fleet operations, is to station in the same system my nodal planets are and simply serve as a military only refuel center so that the in-system gas mines can serve the private sector.
