I like this build but I feel it is extremely reliant on actions which, in my limited experience with the ghost, are easily denied. Playing ABT means you want to be in range 1 as much as possible, so bumping is a common issue. And stress is so hard to shed with this ship. Any stress inducing squad shuts the 41 point combo, 70 if you include Biggs and R2D2. Still he seems the most synergistic choice. Worth it if he keeps Biggs Round for 1 more turn.

Advanced Sensors helps a lot with bumping and with running over obstacles. That or FCS for good ol' fashioned offensive action economy. I think as tempting as some of the other systems are, these are a must.

Not really, You can outmaneuver Ghost to kill Bigs fairly easy. After that the Ghost dies pretty fast with 0 agility (Even if it is taking away a red die). There is a reason you don't see decimators as much as you used to anymore.
