This is the list im using

Darth Vader — TIE Advanced 29 Veteran Instincts 1 Harpoon Missiles 4 Advanced Targeting Computer 1 Engine Upgrade 4 TIE/x1 0 Ship Total: 39

Scimitar Squadron Pilot — TIE Bomber 16 Kylo Ren 3 Lightweight Frame 2 TIE Shuttle 0 Ship Total: 21

"Quickdraw" — TIE/sf Fighter 29 Veteran Instincts 1 Fire-Control System 2 Harpoon Missiles 4 Pattern Analyzer 2 Lightweight Frame 2 Special Ops Training 0 Ship Total: 40

TOTAL: 100

IMO Engine Upgrade is a must on Vader, same with LWF on QD. The Bomber's main task is to block and use Kylo -> Blinded Pilot, after 2 BP he did his job.

This list is very good against 2 ships or lists that revolve around a single ship, but against aces or 4 ships it is too difficult because the effectiveness of Kylo decreases a lot, some advice?

Slightly different. Use the Kylo on a Phantom for a better damage output, and possibly even keep him around. Blinded Pilot your first target, Colzet only needs to be in range three (in or out of arc) of the person that got blinded to spend a target lock to flip their Blinded Pilot back over. Then Kylo can move on for another target where you can Blind a second target, or do the other fun crits. It does pull away one of your Harpoons though. I chose FCS on Colzet because if he attacks the person with 1 Blinded Pilot Crit, even if they can shake a TL, Colzet can still get a TL that he can spend at the End Phase.

Drop harpoons for cruise and run with a bid to beat aces.

I do agree that your Kylo carrier could drop quick. That being said, I think it could be okay. I would personally drop the Harpoons. Keep Vader as-is otherwise (unless you want to switch to Predator, which I might), give QD Expertise, that way they are both stronger late game ships. The shuttle with Kylo is there to ruin people's day/draw fire from the other 2 for a while.

That TIE Shuttle would be a prime target at PS1. It has to get close enough to ISYTDS, which at PS1 will likely be AFTER the first round of combat. You might only get one use out of him before he's vaporized.

As far as using Kylo goes... remember, if your opponent has an high PS ship like VI-Nym, sometimes Damaged Cockpit (PS-0) is even more devastating than a Blinded Pilot.
