There goes Thex again, Bringing a Brilliant light to the key points at hand ^^.
My opinion on the matter is this: While creating an Interceptor class sounds good on paper, (and Kinda in Theory as well) I think I'd have to agree partially with Hawk's input. However Thex (As always) Seems to put up a great rebuttle to it. I think that while Pirate's and Hunter's would use it, it would still be under-used dramatically. Pirate's wouldn't find Too much use for it, seeing as they just sit at a lane anyways. Hunter's MIGHT, but only the Guild, as the solo BH's would then need to split the resulting profit with the Interceptor I'd think. Frankly I love the idea of each House having their OWN Interceptor actually. But Balancing it so that it's not too good at fighting while keeping it's job steady would be an "interesting" job.
Conclusion: Excellent Idea as a Specialist Ship, not exactly an entire Mainstream ship class however.
