I think the Ghost is sort of a trap - yes it has a lot of great options and AC+AB unstoppable 4hits at R1 is scary BUT:
Once you start loading up on those upgrades (+docked shuttle) you get into 70+points territory quite fast. And then its still 16hp with 0 agility and not a lot of defensive options. You're really putting all your eggs in one basket.
I think if they become part of the meta it will more likely be cheaper versions.
This has been my experience running it on Vassal so far. By the time you have a workable Ghost build and an attached Phantom that can actually hold its own when you deploy it, you've spent 75 points. Depending on how you do it you can squeeze a stresshog in there, but it's a lot to dump into one ship. Plus, if you run the AB/AC combo, you have to get the Ghost into range 1 of the thing you're trying to kill. Then, congratulations: the Ghost is in range 1 of your opponent's ships, with zero AGI, and it's not really maneuverable enough to make a run for it and still be effective.
Maybe I still need some practice flying it, but the general flow of my games with the Ghost have been:
1) Run it into range 1 and bump something.
2) Make my AB/AC attacks
3) Soak up a bunch of range 1 shots from my opponent, bringing the Ghost down to about half health in one turn.
4) Run away and deploy the Phantom right before the Ghost goes down.
5) Try to chase down the enemy with the Phantom, which moves before almost everything else and doesn't have a great dial.
The AB/AC combo is fun - it really makes your opponent work to stay out of range 1 - but it's too squishy for my tastes. I'd like to try Kanaan with a rec spec and advanced sensors, and maybe some other builds. The system slot is really valuable, and though the AB/AC can theoretically nuke an ace in one turn, any good opponent will stay well out of range 1. The sensor slot gives the ship a lot of potential, and I'm not sure AB/AC is the right build.
My experience has been different. The first few steps have been about the same - run into range 1, blsat stuff with autoblaster and soak up a bunhc of damage, but in 13 games I've played with the ghost so far, I've only had the ghost actually die in 2 games, and have only lost 1 game so far. My opponents definitely *try* to stay at range 1, but haven't had a lot of luck with that so far (part of that is that I run dash crew so I can move unpredictably and park on rocks, which people never expect).
