Been enjoying this mod tons. As has been stated the pirate Castigator is a sexy beast. I managed to get my hands on a GH Onslaught and promptly slapped Forced Overdrive on it and it is a terror on the battlefield. I just bought the GH Dominator a minute ago and tested in the sim vs a BR Knight that it roasted with ease with Styrix's and Hekaton's. The only one I've found difficult to use so far is the Legion. There just doesn't seem to be enough OP to be able to fit the large weapons and fighters both.
The knight isn't really a comparable ship, as firstly it's a destroyer like the enforcer, and it's more of an all rounder in it being a ship of the line/carrier combo pack, the closest BRDY ship is the Antaeus - which depending on what fit you give it will either handily win or crush it like a bug (the Antaeus beats every normal capital in the sim except paragon )
Carriers OP amounts are currently balanced around 0 cost fighters - whether you agree with that or not, any of the mods which try to maintain relatively vanilla balanced stats, they're going to have horribly OP starved carriers if you try and put the nice bombers/interceptors on them and guns OR hullmods. None of them have enough for all three right now.
