Make them Corvettes, and give Corvettes a small speed boost over Cruisers.
Cruisers are: Combat Speed: 320 m/s | Turning Speed: 20 deg/s | Strafe Speed: 150 m/s | Sector Speed: 270 AU/h
Corvettes are: Combat Speed: 300 m/s | Turning Speed: 30 deg/s | Strafe Speed: 140 m/s | Sector Speed: 240 AU/h
Buff Corvette to: Combat Speed: 350 m/s | Turning Speed: 30 deg/s | Strafe Speed: 140 m/s | Sector Speed: 320 AU/h
Do that, and you'll see Destinies being used again. It also wouldn't unbalance anything, as the Pathfinder and Voyager don't have the mass to do jack. The Destiny is already built to work decently with those kind of stats without being any more OP than they used to be.
Infinity paradox said:Why not turn it into cutter class? There is no T2 cutter, but two cruisers and one of them is useless.
Kixeye love cutters, so they can make another from Destiny
