I ran this list today and pulled off a narrow win. Any thoughts on how I could shore this list up?

I built it with the following Roles in Mind:

VSD II A : Flagship and Ship Killer

VSD II B: Carrier and Brawler

GSD I: Demolisher, close range Brawler

Raider: Anti-Fighter Duty

Faction: Galactic Empire
Points: 400/400

Commander: Admiral Motti

Assault Objective: Station Assault
Defense Objective: Contested Outpost
Navigation Objective: Minefields

Gladiator I-Class Star Destroyer (56 points)
- Demolisher ( 10 points)
- Ordnance Experts ( 4 points)
- Medical Team ( 1 points)
= 71 total ship cost

[ flagship ] Victory II-Class Star Destroyer (85 points)
- Admiral Motti ( 24 points)
- Skilled First Officer ( 1 points)
- Gunnery Team ( 7 points)
- Phylon Q7 Tractor Beams ( 6 points)
- X17 Turbolasers ( 6 points)
= 129 total ship cost

Raider-I Class Corvette (44 points)
- Impetuous ( 4 points)
- Ordnance Experts ( 4 points)
= 52 total ship cost

Victory II-Class Star Destroyer (85 points)
- Wing Commander ( 6 points)
= 91 total ship cost

3 TIE Fighter Squadrons ( 24 points)
1 JumpMaster 5000 ( 12 points)
1 Black Squadron ( 9 points)
1 TIE Advanced Squadron ( 12 points)

Thoughts?

Flechettes on the raider, you won't be disappointed.

Carrier could be a VSD I, saving enough points for another TIE Advanced.
