Very delayed feedback for 0.8.6:
The new Knight design is very pretty. It looks like a bulky ship that can take a lot of punishment, and for a BRDY ship it can, but it's a bit undergunned. It's got a lot of small mounts, but only two mediums and they're hardpoints so far from each other they only start overlapping at 1000 SU. Giving it too many more mounts might start stepping on the Nevermore's toes a bit, so I'd give it another flight deck, maybe two if you want to get crazy about it. That would dovetail nicely with the fighter changes in 0.8, giving BRDY a gunboat/carrier along the lines of the Mora. If you want to give it more guns, though, I'd really like it if the central mount was upped to a medium for 360° PD coverage.
The Bolide and the Comet are confused as to whether they're main guns or supplementary guns. As far as I can tell, the point of putting limited ammunition on guns is to force them into being a supplementary weapon, a powerful weapon that you should only be firing some of the time and that should probably not be the only weapon on a ship, sort of like missiles or the Antimatter Blaster. Having a gun with limited ammunition, but more than enough ammunition for very extended engagements defeats the point of limiting their ammo. Even without Extended Magazines, the Comet has enough ammo to constantly fire for 5 whole minutes, and the Bolide can fire for almost 7; by then everything smaller than a cruiser is out of CR anyway. Either they should have significantly lower ammo and higher fire rate so they're a powerful gun you can only bring out against specific targets worth using the ammo on, or the ammo count should be removed entirely and the stats balanced around that. As it is, the limited ammunition doesn't matter for anything smaller than a cruiser, because the ship will break down before the gun runs out of ammo.
I like the Voidspear changes a lot. They're like the unholy spawn of a Salamander and a Hornet, and I love them so much. I had to stop using my Voidspear Archers because they kept running too far forward and getting themselves killed in large battles, but while I was using them they were very effective at long-range pressure. Voidspears work best in large amounts so you kind of have to build a fleet around having Voidspears on all of your ships, but single medium universal mounts being common on BRDY ships make it both possible to do so and effective when you do.
