I also think that freighters are useless as much as light fighters. How about changeling tags and profits for smuggling. i.e smuggler ID would have limit for freighters but profit for lets say Cardi run would be 4x bigger.
Looks nice but that would cause lots of troubles with pirate unlawful factions who would need to use freighters for trade only.
Other words nothing will be done with it and in the end freighters will be use only by players who are not interested in profit but in good RP.
