Dev cap ships don't have to wait to warp, which is obviously unfair to other players.
Yes, but it was totally fair to those players that had no cap ships for six months+ before the workaround was even implemented due to the bug.
The why is a bunch of people whined about it, so it got removed. Should have been removed sooner. Fairness has nothing to do with it, it was just a bad mechanic that was abusive of a players time for no reason. (yes you can argue it limits jump hauling rates, I will counter argue you can set up a loop of jump haulers to origin run by a single player and remove that time anyways.)
