Giving the barge at least a small max speed bump is needed since pain the ass NPC's can keep up with a barge at cruise without even touching their afterburners. The new changes are punitive at best.
And the reason for removing lane access since it's "intended as a deep space ship, where their aren't any lanes" is a hollow argument.
How would a barge even get to deep space with a max speed of 99 meters per second since that's literally only 10x the record human running speed?
