Specifically the normal pirate line: Frigate, Cruiser, Battleship. They already have ship models, but the introduction might encourage CCP to update them.
Rogue drones primarily do EM damage, so the easiest thing would be to just use bonused lasers, and maybe a few missile hardpoints. Maybe give them the ability to hack other people’s active drones and steal them.
My reason for suggesting this actually has more to do with getting rid of the massive isk faucet that is drone bounties, than it does for actually caring about flying Rogue Drone ships, but I’m sure some people would enjoy it.
Over 10 years ago (12-13?) CCP changed Rogue drones from dropping drone goo to giving bounties, because the mineral glut from the drone regions was causing a large number of supers to be produced. Thus the gun mining loophole was closed.
That said, all of those old alloy items are still in the game, they’re just no longer dropped from rogue drones. So if we went back to not having bounties on rogue drones, but have the wrecks salvage into the alloys, it would be easy for ccp to put those back into the drop table for the wreck salvage.
The twist here, is that drone alloys would no longer reprocess into base minerals, but instead be the base materials used for producing rogue drone ships and components.
Alternatively, instead of requiring the wrecks to be salvaged in order to gain anything from killing them, rogue drone rats could drop t1 equivalent rogue drone modules that could be reprocessed into the base drone alloys. So the modules would fill the same role as the old drone goo, but could also be functional modules for a capsuleer rogue drone ship.
The bpcs could be created through an invention process from data cores retrieved from rogue drone structures in anomalies, signatures, and missions.
So, we’d close the isk faucet, create isk sinks from production fees and market taxes, and have new toys to play with. And, old players would have new skills to train.
