In my opinion, on the subject of B/S, the shield is fine, slow re-gen makes up for the sheer size of the shield. But what I do think is needed is a higher cruise speed, they cant thrust, and they cruise at the same speed, surely a B/S with a big engine like that would exert enough power in the 0 friction of space to propel itself much faster than any fighter. This would avoid the problem of trade lanes, and not being able to get anywhere fast. Any idea's?
