I was brainstorming some ideas at how to fight the Ghost while I was at work today, and I have one ship that might give it a run for it's money. I still need a squad to go with it and I am sure it can be tweaked but think about this set up here.

Rear Admiral Chiraneau

Stay On Target

Agent Kallus

Navigator

Engine upgrade

Now you don't know what kind of Ghost you are going to be fighting, but for this I just assumed Hera, she seems the most slippery of them all. Chiraneau outranks her in pilot skill and she can't take an EPT, so you have an advantage there, freeing up your EPT slot. Kallus is there for both flavor and efficiency, if you have him on Chiraneau's ship, you pretty much never have to worry about focusing.... the Admiral's eye to crit and Kallus' eye to hit on three dice is promising, especially so with a target lock.

Hera is going to be hard to pin down however. I thought about using the intelligence agent here, but with no chance of her moving after your decimator, you don't have to worry as much about that. Instead to match her moves, we're going to go with Navigator and Stay on Target. Navigator let's you effectively change the speed of your banks, turns, and straights as long as you keep their bearing, and with SoT you can change direction entirely as long as you keep the same speed. The only trick here is you must use navigator first, before you use SoT. It is tricky, and lands you a stress, but it should allow a big fat decimator to fly wherever it wants.

Fighting Kanan will be similar, but you do not have to invest as heavily into changing your dial. Against Chopper? The navigator and SoT will help, as his stress ability only activates once combat starts, so as long as you are not touching him his ability is wasted.

Unfortunately this ship is going to clock in at 57 points, which doesn't leave a lot of room for backup.

Just brainstorming, lookin for more ideas.
