Spot the difference? Its only small but its there, this is what the op is talking about, small changes that show the ships are improved versions of their predecessors rather than carbon copies with larger numbers in their ini.'s
I am for these small aesthetic design changes, but if the vanilla models where brought up to standard and the mkII's removed that would be cool as well. We'd still have civilian ship-lines for those who want to be challenged by low lvl missions.
