Cheaper than an ASP?!?! There are far enough cheap ships! ASP and Vulture are in one bracket than we got Dropship and Clipper in the next bracket and than Python....
I rather wish to see the Diamindback between Dropship/Clipper and Python at around 35 Million... that would be perfect!
Nothing wrong with cheap ships. If I were developing the game, the Diamondback would be a combat focused Asp. Think same price, similar speed, jump range, and armor/shield values (just reversed to fit the theme of combat ships having stronger shield values over armor values). The major departures would be weapon hardpoints (3M, 1L) and internals (1x C5, 4x C3, 2x C1).
All the art and hints we've seen simply don't support the idea that the ship will be 20-30m Cr. I'm probably wrong, since they tried to do that with the Vulture. It's a powerful ship, sure, but nothing about it screamed 20 million credits.
We're still expecting many more ships beyond the Courier and Diamondback. There will be something to slot into the space between the Asp and Python, eventually. We still have the Clipper and Dropship to sit in that space, and ideally there should be one that doesn't require a navy rank. Perhaps 1.4 will focus entirely on filling out the ship ranks.
