I don't yet have a fleet because I don't have a gaming machine nor time to play, but I intend to by fall so I will share what I am interested in.
For a dogfighter, I am waiting to choose between the Ghost Tracker Hornet with a pair of the big BEHR C-788 Ballistic Cannons , or perhaps a Hurricane version of the same. I am leaning toward the Hornet but we will see what happens when the real numbers for hull, etc. come out. The way to run a Ghost ship is with shields down, so you want good hull. The Hornet looks like it fits the bill for a dozen different tasks, and that's what I want in a dogfighter. It is a big departure for me to fly this instead of the Sabre, but I really like those BEHR cannons. The only exception I can see is if when we have PVP data to look at, and if close-in fighting is a thing, the Sabre with 4 Pyros looks like it will be extremely hard to beat. We'll see. It matters much to me the stealth capability of the Ghost Hornet v. the Sabre.
I plan to own all four variants of the Vanguard, and several of some kinds. I can see myself flying second seat in a Sentinel and directing attacks from there. That is my standard "lets go make some trouble, steal some ships" plan, though I will probably only buy one Sentinel and take possession of the rest.
I plan to buy a Prowler which gives me a Hoplite early on to team with the Sentinel. I just love the Prowler and it is replacing my intention to own a Redeemer. My problem with the Redeemer is that for 5 players, you can fly 3 Vanguard and the Redeemer would certainly lose that fight. For combat ships I always think of firepower per player, and it is certainly more efficient, and more my playstyle, to fly something that has much bigger guns than the Redeemer, and can go invisible. The recent figures have the big S4 and S5 guns with much more power, and range. The difference is so much I cannot see putting S3 weapons on a gunship and that is what the Redeemer is stuck with.
If I have to pick one ship that I would consider home, it is the Polaris. I can't wait to buddy up with friends flying the Carrack and StarG. Those three and a few support ships and we can explore Krell space, or terrorize the Vanduul. And I am looking forward to the mini-game around the Polaris pool table.
