Leaving aside the question of whether FCs are designed for communities or solo players, let's take a look at the math:
Regardless of how many alts you have in your squadron, you can still only fly one ship at a time, so given that the maximum squadron size is 500, which means that it'll take a single player 8 HOURS to do what the full squadron does in a MINUTE.
Now the Gnosis jumps 500 LY, so taking that as a benchmark, if refueling the FC takes a full squadron a minute, they would be able to get their FC to Beagle Point in a little over 2 hours. I think we can therefore assume that FDev intend it to take more than a minute to move a carrier 500 LY. So how fast should carriers move? Well the Gnosis only jumps once a week, so I'll again take that as a benchmark. I think 5 hours per week is a reasonable estimate for play time for an average player, and I'll also assume that FDev are happy for a mid-sized (250 member) squadron to move their FC 500 LY per week. So that's 1,250 man hours to move a carrier 500 LY.
Those of you wanting your own, personal, fleet carriers to take out into the black to explore, you're looking at 2,500 hours just to get far enough out to start getting first discoveries.
Now it may be that FDev set the limits lower, so that a 25 member squadron can move 500 LY per week - but you solo players are still looking at 6 months to move that far, and a full size squadron would be able to move 10,000 LY per week which basically means they can teleport around the Bubble at will, which I can't see FDev wanting to happen.
So everyone may be able to get your own personal carriers, but I'm pretty sure they're not going to be able move it far.
Since we're speculating, i think there are a number of specific factors working against this.
- Doing this will wake the dragon. The mainstream steam review crowd. Frontier are mortified of this crowd. Think steam reviews, the gnosis, the fss in the bubble, removal of credits, removal of rep. In the end, Frontier have proven this is the only demographic that they move the mountain for, and adding a grind doesn't make them happy.
- Im not sure if frontier have a measure internally of cost benefit, but i think even they would balk at over a years development on a feature for barely a few thousand players. That defies all logic. But given they're so resolute about everything they do you can imagine all sorts of things.
Course we don't know, but could land either way.
