That I obviously know.
What I want to know is what influence the refit price to understand how to construct my ship in a way they can be built in the same yards.
As an example from the classes above.
I have a refit cost from the Attila ship to the Galaxy class on about 520 build points and a cost of 93 build points to refit a Galaxy ship into an Attila ship.
I would like to know what drives thise refit cost. It would not have to be specific just enough to understand how it works and why.
