The mining drones now have about 4 times as many salvage modules and still work great. With the new fleet upgrades, these little drones can really eat through a whole field of rocks quickly.
Mothership function is largely unchanged, but the rear end was shortened for slightly improved maneuverability, some of the lines have been cleaned up with wedging, and a few minor decorations were added. Total cargo of mothership is down from 150K to 124k as a result of the maneuverability improvement, but she still holds a lot of cargo for a relatively small mining vessel.
The larger drones give the power ring a slightly chunkier look, which is still pretty attractive, though I preferred the thinner drones aesthetically.
