Actually, Prelude, I expect if they were bolted face-to-face, you'd be able to turn on one engine or the other and gain something resembling Super Maneouverable, at a really low speed, like 4. The broadside would be hideous ... against hull 5 ships.
And, I guess, that's the point. So the Raiders get such a thing. So what? It's slower than dirt, of limited range, and probably at Battle or War level. Not exactly terrifying. It's not even as nasty as one Primus. The Primus would carve it apart. If its slower than a Nova, it'd be speed 4 and just betting for that -2 or -4 speed crit to make it an irrelevant ship. And even if it gets to the Primus, it'd get ... what, 8 hits or so? The interceptors will turn that down to about 4 hits for say, 3:3 and a crit? That's my payoff? Big whoop.
The Raiders need something, and, help me, this is just a start. They'll need a lot more than that -- something actually cool at Skirmish level would be a start, that Strike Carrier doesnt' qualify at all! -- to finally make a fleet out of it, because now, it's wreckage-in-waiting. Allies or not.
