Lately I've been running more and more imperial squads, and I personally love the tie advanced (mainly Maarek Stele). I started a list but I'm not sure where to go from here:

TIE Advanced: · Maarek Stele (27)

Predator (3)

Adv. Homing Missiles (3)

TIE/x1 (0)

Advanced Targeting Computer (1)

TIE Advanced: · Darth Vader (29)

Swarm Tactics (2)

Engine Upgrade (4)

TIE/x1 (0)

Advanced Targeting Computer (1)

70 points

Not sure what to do for the remaining 30. Howlrunner and an AP, or a super up interceptor, or another advanced. I'm simply unsure.

There are a ton of options that can fit into 30 points. An interceptor, another named Advanced, palp on a shuttle, another mid 20s ship + a hull/shield on maarek, etc, etc.

Since you are running swarm tactics on Vader, I would suggest 2 Epsilon piilots. They are only PS1, but vader can boost one of them to 9 if you need to. Also, running a pair of blockers really helps keep the 2 advanceds on target and stops opponents from blocking them so you can approach more aggressively without fear of losing actions to bumping (while doing that to your opponent...)

My apologies what I said was incorrect.

I would drop swarm tactics from vader. He has a big target painted on his back and if you run him in formation (because of ST) then his moves are predictable

since you like marek may i suggest:

vader+VI+EU+Adv Target

marek+Adv Homy+VI+Adv Target

with remaining 33 points:

a) rhymer with adv homy and ex mun+ VI

and then twin ion engine on marek

b) carnor jax+VI+AT+stealth

c)drop advanced homing and get soontir

d) wampa

scourge+VI
