^ i agree with this .
Fighter/Freighter only jump Holes and Docking point only they can land and sell some expensive cargo would be good thing ( Like Black market amno to Leeds Bretonia rebels sells for 11000 , and if there is also Freighter Jump Hole that shorten distance from Berlin , Freighters will be in high demand ) .
As for changing abilities of freighters , in my opinion they are fine ( except few exception ) , there is more important maters to deal .
