To be honest...good. When Fleet Carriers first came out I didn't want my FC presence advertised to all and sundry, I wanted to be all alone in the dark, not with a huge sign above my head shouting, "here I am" to everyone in the galaxy. I expressed my dissatisfaction at the time but unfortunately they went ahead with it that way and didn't provide a private option for us who just want to be alone and unfindable! Having you FC findable should be a player option not a compulsory game feature!
I recall that one of the original issues with Odyssey was something to do with FC loading of... 'Something' that was causing massive crashes - pretty sure it was in the first few days - they identified it, and IIRC, they switched it off temporarily.
Off-topic(ish) but related - I'd also like the ability to switch off FCs from the system map - is this done yet? I have no interest in seeing or visiting any. Sorry to sound a stalwart!
Originally, I wanted two options - 'just me' and 'open' - because I knew that most folks wanted the open option where your FC was always there, and I just wanted an FC with no upkeep and just house my ships for exploration/movement around the bubble - no trading, just store ships and repair them. I'm convinced now that a third option, 'group' would also be awesome - so only when you or members of your group, the FC becomes visible.
It's the reason I never bothered to get an FC - the upkeep (despite the fact that you can save enough to keep you going for a few years+) that put me off - it was completely out of my remit to go for such a design decision. Which is a shame. Then again, it's well known that players have no involvement at all in the design decisions of the community, going back to the days of severing the DDF. Oh well, grin and bear it
I wonder sometimes though what the impact would have been if they'd have tailored FCs to three different modes of use such that you didn't have persistent FCs. I've been to systems where you have to scroll several times just to view different parts of the system map, because over 99% of the system map is FCs.
Anyway, +1'ing you, despite the fact it's probably too late and we've got different ideas for solo/group/open FCs... I doubt things will change, either way!
