I am new to X-Wing, and I have only used lists with small ships.

I was wondering if a list with a large support ship and Aces(or multiple small ships) could be viable

here is the list I was thinking about trying.

I like the idea, reduce agility by one and roll 10 dice, but I see a major problem, your Fenn doesnt have Autothrusters which are pretty much mandatory on any ship with a boost as it will help you alot defensively. You could free up the necessary 2 points by dropping maneuvering fins and intelenge agent.

I have seen alot of people run Weapons Engineer on Lattz, but as my personal opinion I don't think it's that great, you'll want to always be shooting at the same target, so you'll have a target lock unused on a ship. I think it'll only be useful in a round where you kill a ship and you can reduce the other's agility for the rest of the attacks. For those 3 points you could up grade something else or switch to Dengar (crew), because most time you'll spend your lock to reduce agility and so you'll only have a focus for a modifier, if you even have one, so with Dengar you can spend your lock lowering agility and still have rerolls during the attack.

Now that we have freed a few points, I'd say we can upgrade Fenn's mindlink to push the limit. Although mindlink is cheaper and easier to use it means Fenn is dependent on the other ship with it, and if it's a ship that can withstand a beating (Ventress) or that's always running away (Inaldra) then it's good, but Talonbane is going to die quick, with some luck he'll do alot of damage before he dies, but pretty sure he will, as the Kiraxhz isn't the most resiliet ship, and when he's dead, Fenn is almost dead weight, as he is limited to one action which for Fenn is no bueno.

I never played alot of Kiraxhz as mine tended to die on the first/second round of shooting so your Talonbane build seems ok with the points you have, although if you follow my previous suggestion, you could change Attani to Veteran Instincs or to Fearlessness, depending on what you prefer. Then you have a choice, do you want a 1 point bid to try and choose initiatie (and give it to your opponent if he has ps9)? Or you don't mind going for 100 points? Honestly 1 point bid might be better than no bid.

If you prefer to have a bid, keep Talonbane as he is but consider changing Vectored Thrusters to Glitterstim as it will allow you to jump into Range 1, target lock as an action, activate glitterstim and have a 5 dice fully modded attack. Vectored Thrusters is good don't get me wrong but the change might be good too.

If you dont mind going to 100 points then the change to Glitterstim could be done without touching Vectored Thrusters.

Honestly, if I were to use a support ship I would most likely use a jumpmaster as a bumpmaster, a contracted scout with intimidation(elite), intelligence agent(crew), EMP device(illicit) and ion projector(mod) and then upgrade the rest of your ships to taste.

Sorry for the long post, hope any of it helps.

I revised the list.

With your opinion on autothrusters being a very strong defensive bonus, I squeezed points to put it on Talonbane and Fenn Rau

I thought about it and Latts will probably be able to target lock as her action almost every turn so i dropped the security droid.
