If the D6 / D7 is not being used in favour of another ship - does this not point to an issue with that ship or more liekly its relative worth? Putting the cost up to be honest just irritated me and I had to try and find other ways of squeezing the D5/D5W in. If on the other hand the points had gone down for the D6/D7 then I would look again at the ship and consider it on its revised merits. If it does not matter which ship goes up or down - surely its better to put down the "inferior" ship?
What am I missing here?
