The best things in life aren't things.
The other thing i have put together is a scum list Putting secondary weapons on Talonbane negates half of his pilot ability as you get no range bonus when attacking.
Will this even work? I have never played a tournament, and have just played imperial lists before
Talonbane Cobra (34)
Kihraxz Fighter (28), Assault Missiles (5), Munitions Failsafe (1)
Palob Godalhi (24)
HWK-290 (20), Blaster Turret (4)
Aggressor (36), Determination (1), Sensor Jammer (4), Tactical Jammer (1)
I dislike Blaster Turret. It's too easy to shut down your ability to shoot. Though I suppose Palob can steal the token. I would just not take Focus actions with my ships if I was facing this Palob though.
I think your IGC is too weak and defensive. You're using tactical jammer on an attack ship to protect two weaker offensive ship.
Palob is a great support ship but I think you need to focus on one of either Talonbane or an IG as your main threat and spend the rest of the points supporting that ship.
