So many people reading, but no comments? Can someone tell me if my build is good or not?
It's pretty good. You can't deny how powerful it is to get 3 actions (focus, boost to arc-dodge, and get a free evade from C). It's a lot of fun and can do quite well. My standard load-out is
-IG-2000 (0)
-Push the Limit (3)
-Advanced Sensors (3)
-"Mangler" Cannon (4)
-Inertial Dampeners (1)
-Autothrusters (2)
-Seismic Charges (2) [only fits on one IG-88]
Yours has better damage output with the Heavy Laser Cannon, but isn't as good defensively because of the lack of Autothrusters. But I think with what you have (or will have with a shuttle or 2nd E-wing), it's a pretty strong list. The thing is that Autothrusters is so perfect because then you can try to stay at range 3 with your cannon and get an extra defense die when your opponent attacks while your opponent doesn't get the extra defense die since you're using a secondary weapon anyway. Then you add the effect of turning a blank to an evade with your Autothrusters. It makes the Aggressor a great sniping vehicle.
[What follows is more about where to go in the future.]
Basically, once you add Autothrusters, you'll have to sacrifice something from your list. I've always dropped the cannon down to "Mangler," but I always feel like I'm struggling to push damage through, so maybe I should switch to Heavy Laser Cannon. The thing is, Autothrusters do so much for IG-88 that once you have those, you'll always want to make room for them. If you drop the one Seismic Charge from my build and take out Inertial Dampeners, you've freed up 2 points on each Aggressor. That's still not enough to upgrade "Mangler" Cannon to Heavy Laser Cannon. You can use Fire Control System instead of Advanced Sensors. Now you can fit the HLC. The problem is that you won't use Push the Limit as much because you can't clear the stress in the same turn, but with all the green on the Aggressor dial, it's still not a bad upgrade.
