My feedback:
First, I must say it feels good to play with BlackRock again. I bought Starsector some 4 or 5 years ago, when it was first made available for purchase, and your mod has since become my favorite by a significant margin, and that's saying something when considering the wealth of talented modders on these boards (Tartiflette ftw!).
I think it had been 1 year and a half since I last got my hands on the Nevermore... I was giddy with joy when I first did yesterday after such a long time.
By the way... Is the Nevermore B no longer a thing?
I see a few BlackRock weapons still have an ammunition count. Are these legacy elements meant to be changed or there by design (The Medium Scalaron Blaster for instance) ?
The fighters:
The Krait does feel much much powerful than every other fighter you have available from BlackRock in my experience. But some are just as good if not better already in the base game (warthog indeed says hello) so I can't blame you. Fighters in every mod feel pretty damn OP in general. If I wanted to min max I would only ever get carriers in this version of the game.
The Mosquito feels maybe a little weak. My mosquitos seemed to have trouble getting back to my carriers quickly enough for a refill. It might have had to do with their extreme speed; they turned around their motherships for a while before actually docking/
The Vespa missed their torpedoes on immobile, large ships 2/3 of the time. That's... quite an extreme miss rate. Seemed to me the speed/manoeuvrability of the craft was the issue again. They couldn't properly align with their targets before firing.
I didn't really try the others yet, so I'll do that before I say more.
Congrats with the mod, again.
