Been trying out some ships from this mod, figured I'd give some feedback.
Please note that these are for the default loadouts, unless otherwise stated.
Banshee: The energy broadside is kinda terribad, on top of it being fixed, and thus awkward as hell to use, it also recharges slowly. There's a reason the conquest no longer has a fixed broadside. I'd personally switch it to limited arc turrets, similar to the conquest.
Limited shield arc mean if you are on the frontlines against any appreciably threatening force, you are likely going to die. You can only block one small angle, and your arcs of fire are limited enough to make it difficult to quickly deal with multiple threats approaching from your flanks. So any more then two enemies at once is untenable. Your shield is so efficient you can probably laugh off one ship though.
The engines really aren't that amazing, despite the description. It's not slow... for a capital ship, but neither is it that fast for a capital ship. This may be colored by my use of other mods though.
Probably not a ship I would personally use very often, given I'm not terribly fond of missiles, and the awkwardness of the broadside. I've yet to see how the AI handles it either. I may try playing with the loadout a bit to see if I can pull something I like out of it, but otherwise not a personal flagship. Pity, because it looks pretty rad.
Tldr; Definitely not a frontline capital ship, at least in the default variant. Passable midline command/fire support ship. Not too strong... although for its looks and pricetag I was expecting something a bit more... impressive. Maybe even a bit on the weak side for a military-grade capital ship. Shields, speed, and the broadside might maybe need tweaking, although that's just a personal opinion.
Singularity: Its efficient shields make it eminently suitable for escort roles, even without weapons, distracting an opponent, and tanking them nearly indefinitely. It also makes it excellent as a strike frigate, it can tank all damage coming from its target as it moves in.
Its automated nature means any damage it takes costs you no crew, making it good for tanking, especially on prolonged voyages, I imagine that will make it even better when the campaign is fleshed out.
However, when looking at it from a player controlled perspective, this becomes a disadvantage, no crew means no elite bonus to engines, shields, or flux.
Fixed frontal weaponry, even if powerful, mean it's terrible at dealing with multiple opponents at once by itself, turning to fire on one means nearly completely exposing yourself to another, leaving your engines wide open. This ship definitely works best in a group or 1v1 role.
Tldr; A much simpler analysis. An excellent escort, hunter, and strike frigate. Lack of crew, limited arc shields, and slow firing burst weaponry make it unsuitable for solo use. Neither overpowered or underpowered.
That's all I've extensively tested out so far, might post more if I get the hankering to put any others through their paces.
