Also on the fact it can't fit both shields and AFMU. Also on the fact a pure trader in its price bracket outranges it. Fuel scooping speed is almost as important as range for explorers. Obviously you can explore in any ship -- I know someone who went to Sag A* in an FDL. But just as jump range and cargo size is important for traders, fuel scooping speed, range and supercruise turning speed are important for explorers. Since the diamondback was advertised as a dual role combat/exploration ship, it is a reasonable supposition that it would have stats to support both roles. It does not -- it is really bad for exploration.
Do you explore, Mister5150? What's your exploration rank?
trailblazer if im not mistaken, im an occasional explorer so i understand your argument for fuel scooping it is quite a pain to have to do it often and have it take forever, however have you flown the db? it is quite awesome additionally im certain other factors play into when and how often you have to fuel scoop based on mass and fuel consumption.
