As a shipping faction, instictavely I agree with the larger vessels with cargo size to match.
If it gets agreed upon, maybe there can be a trial period. Like a month or a week. During this time issues can be picked up and possibly sorted. Like for example model x was used for these super transports, but is either stronger than wat it should be, or weaker.
By this I mean hull strength, shields, nano/bats, weaponary, wil they be able to use jump drives, docking bays, where can they dock or not dock. Etc. like would a super transport be able to dock on a station due to its size or only planets.
Given that if they as big as battlecruisers, their ability to dock with trade lanes does decrease compared to their smaller counterparts. Will this be taken into consideration to make the hulls stronger or give a certain set of weapons to fend off small vessels?
