He means that Phantoms most likely roleplay more than they power trade.
Thus, it might take them years to buy a normal battleship.
Maybe make the price cheaper?
I am of the opinion that this ship is great, and unique, but could really use some more width.
Also, you might consider a phantom battleship that was basically 2 of these put together, and rotated like an X. Not like an X-wing, but more rotated like a real X.
