Not really sure if its bug or ballance related thing but anyway:
Farmer Alliance and Hogosha have access to Gaian and Corsair weapons on 90% by ID techchart, but their ships - Black Dragon, Irezumi, Mamoru - cannot use any of Gaian or Corsair tech, it gives 10% on power core regen. Currently want to request allow this 3 ships to get access to Gaian weapons on 100%, so in result we will get only ID nerf - 90% regen. http://discoverygc.com/forums/showthread.php?tid=130076
^this is Alliance) RP with Gaians about exchanging ships and weapons as RP background for this edit.
Regarding Corsair weapons I actually discovered that Corsair ships cannot use Farmer/Hogosha weapons as well, only Correo have this ability. Is it possible to give both Farmers/Hogosha and Corsair snubcraft sized ships use weapons of eachother? They are close allies after all.
