Greetings All. With the advent of BFG2, and the focus of the timeframe, it isn't surprising that the Gloriana class would show up. With the presence of Macragge's honor, other factions will need similar ships if there is to be any pretense of balance (especially after BFG1). So I open this thread looking for suggestions and ideas, as I have not read all the books and thus cannot think of anything for several factions. So without adue, the factions.
Imperial Navy: This lot will likely share the Gloriana, and I say likely as I do not recall if they can still be made
Space Marines: Gloriana, as per trailer
Adeptus Mechanicus: As to not have the same vessel 3 trimes, likely they will use an ark mechanicus, which as per Gods of Mars may get silly
Necrons: The Cairn will fit in just fine here. Its far to powerful to be compared to normal battleships (as per battle of Amarah it oneshots them) and also far too tanky. Honestly if the substitute in a heavy cruiser or the Elusive Kopesh class for the "Normal" battleship class it would be a better option.
Chaos: Looks like even more Gloriana, as there isnt really another comparable class they have, just a bunch of one offs like the Planet Killer or the Termina est, neither of which measure up in ship to ship combat anyways.
Aeldari Corsairs: Corsairs are kind of strapped, they have the Void Stalker but it wont cut it (especial now that there is an entire faction whose weapons go "Lol what holofields" and are faster than them, if less maneuverable). They will have to make something up here.
Aeldari Craftworld: Same problem with the corsairs above. Best i can think of is that they use a small craftworld like Lugganath, as craftworlds do vary in size and Potency.
Drukhari: These guys should be fine, as their entire navy will be in the midst of a revamp anyways as currently they have a grand total of TWO ships, which is a tad small. They likely have something or the other given the size of their raider fleets, and will need it as their holofields are ignore by one faction (shadowfields I think the variant is called) and their mimic engines are ignored by two (Tyranids and Necrons)
T'au Protector Fleet: (laughter can be heard)
T’au Merchant: (Hysterical laughter can be heard)
Orks: A space hulk should do it. Alternatively I wouldn't put it past them to make some horrifying abomination out of dead ships and squiggly bits. And then paint it red.
Tyranids: A large hive ship should do, with a normal one as a normal battleship. They can go from battleship sized, to the one in the Trailer sized (big enough that its mouth was bigger than a 15ish KM necron ship) to big enough to literally eat a moon.
Thats all I can think of at the moment. Maybe you guys can come up with something else. Thanks for reading.
