to answer some of your obsivatoins death srtar comes with free star destroyers and tartans the empire has more of a risk loosing shields because mon cals shields cant be targeted the aclamitor is more well rounded and has a torpedo launcher, then the vsd, but its a tech one, so sure it sucks. i think the nebulen b has antie corvette and antie fighter guns while the asualt frigate has anti corvette and anti frigate guns
