Not sure if you guys are joking, or not, as I think some of you were around during that time. But in case you didn't, and also for the benefit of newer player who were not:
WAY back in the day (like in the version 3.xxx days), mobile repairers, now mobile space docks, could build "tugs" that would seek out and tractor in your own (and allied if allied assist was enabled) ships with an HP below a certain threshold (the threshold depending on the kind of tug built) and would pull them close to the nearest mobile repairer. I think their was a tug class that keyed off of engine damage as well. It would release the ship once fully repaired. As it was a tractor, the ship would resume with its previous orders after it was released.
Sadly, as these tended to be kind of "finnicky", and from what I heard, they always were ever since they were introduced, they were removed before 4.000 IIRC.
It would be nice to see them back, as they did help make "low HP ship retreat micro" much less painful, but the gain for putting them back in may not be worth the dev cost of making them work well. IDK.
