... Yes, because when we want to move cars around what we do is ship them in pieces to a local factory, assemble them there, and drive them to the lot for sale. Oh, wait, no, sorry, we don't do that, we put them in a bigger vehicle and ship them that way. Also, it's not like these multipurpose ships would suffer from allowing people to have something to allow combat vessels to travel. Like, the FDL and the Python are roughly equivalent in cost. And yet despite being a combat oriented ship the FDL doesn't really out preform the python significantly, and it has the added bonus of being more or less crippled for jump range. The same goes for the Corvette and the Conda. The corvette is even a little more expensive doesn't outperform the Conda in combat that much despite being nominally a combat ship, and limps alnt at roughly half the anaconda's.
I get that at one point, the argument was that these were the biggest, most expensive ships, but they are not any more. We now have bigger, more expensive ships, if the idea is that ship price should determine the effectiveness of the ship, then that should be what happens. I agree that a sidewinder should not be as effective as a cobra should not be as effective as a python. But when we compare like to like in the price tiers? Then I assume, the idea is and should be, that the multi-role ships should be decent at either role but be outproformed by specialist ships, not be the thing everyone aspires to because they are the best thing in the game.
