An inquisition club member has been encouraging me to play resulting in me playing a lot of imperials to fight his rebel fleets. Last night we tried out the new carrier and Admiral Sloane to great effect. Here's the list if you're interested. The squadron ball was hilarious.
Gladiator 1st class with Sloane, Admiral Montferrat, Demolisher title, Ordnance experts, Assault proton torpedoes, Engine techs.
Gozanti with Suppressor title, minister Tua, ECM, Expanded hanger bay, bomber command
Gozanti assault carrier (the other one), expanded hanger bay, comms net.
Quasar with stronghold title, expanded hanger bay, boarding troops
4x Tie interceptor squadrons
4x Tie bomber squadrons
Missions are Most wanted, Fighter ambush and Superior positions.
Dengar stacked with Howlrunner meant the interceptors were effectively counter 4 and usually obstructed due to the stronghold title. The ships were a little awkward because of how much they wanted to bunch up and you might want boosted comms instead of expanded hanger bays on one of the gozanti but that makes activating all the squadrons a little harder.
Sloane seems a very useful admiral when bringing enough squadrons to really benefit from her abilities. All those squadrons with a single blue die against ships suddenly get a lot better when they spend tokens and get a reroll. It definitely works best with high volume though.
I quite like the original Vader list but as you point out, disposable capacitors are for small to medium ships only. That does mean that Victories can take them and a Vic II can put on a very respectable showing with them. Having tried boarding troops I'm not convinced about their usefulness due to the proximity needed to utilise them. However there's no denying how brutal they become in concert with an ISD using the avenger title.
Best of luck for the Kirton event.
