I would definitely limit access to the weapon. I wish CDs were in classes like guns and missiles, so they could only let certain ships use them. Still, all House Police need it, and pirates, as long as it's not used for military stuff, just piracy. I just think it would be practical for capital ships to use it to take in POWs, as after-battle cleanup takes forever, but mainly this technology should stay out of military PVP hands.
This won't be like an EMP, because it needs to shut down the ship that is using it too. I kind of like the uncertainty of it: in real life, a cop that just pulled someone over wouldn't know if there was another criminal waiting to shoot him as soon as he got out of his car. I really like that it makes a sort of stalemate, and the only way to get out of it is for one player's friend/escort/backup to show up first, or someone to RP a compromise.
Am I right in thinking most pirates use a combat freighter? I used to pirate in a Correo, so it would have enough space to hold some cargo. If CDs were reorganized into classes like the higher level turrets, combat freighters and cop ships could be able to use this weapon while normal fighters couldn't.
