If both figures hold, then the BMM renders the Privateer completely pointless, not the Kraken itself, but the *Privateer* variant.
The Kraken-P is not a generic cargo ship, so the comparison is moot.
All signs indicate that the Kraken-P has both 1) general cargo storage, and 2) retail shop 'storage'.
By retail shop storage, i mean that every one of the Kraken's various stores will have some capacity to store the goods that are being sold there, separate from main cargo.
I'm familiar with other MMOs where player-run vendors are a thing, and see it like that. We'll have stock items in 'shop storage' on sale, which is different than general inventory elsewhere.
In this regard, the Privateer is NOT 'completely pointless'. Its storage may just be in a form in which other players can interact with it (buy it) differently. Unlike storage of a base Kraken.
Remember, LTI on ships today doesnt mean that it is preserving the best outfitting of ships that we can possibly achieve in game ....
Privateers will be useful when someone blows up, loses their prized ship build out, doesnt want to fly across half the galaxy to find the parts again, and can just get them from a Privateer in the fleet.
By comparison, the regular Kraken is just a Hull C with an added landing pad and guns. Nothing more special. It just an armed hauler to park ships on. The Privateer is more.
Oh and moving forward, everyone that says Kraken-P's are completely useless hereby pledges to pay double when buying items on my ship! LOL.
