Once upon a time, Frontier released Long Range Hauling missions, some legal, some smuggling.
The most profitable ones were mostly available on remote, far away systems, as the reward scaled not only with rank, but with distance to destination.
They were fun, you had to equip a vessel not only for distance travelling but for fighting pirates and evading cops. You would travel to a remote, far away system, pickup a handful of missions, and then you were commited for 3 or 4 hours of high speed chase from pirates and cops, always on the clock, with a lot of far away destinations waiting for you, trying to scoop while being chased by pirates, trying to jump while being chased by cops. Then you had to enter stations undetected, land on outposts undetected. After a 3 or 4 hours thrill, you could finally put your feet up and rest.
You had to use fuel scoops, heat sinks, silent running, fighting, fleeing, navigating unscoopables, looking for gaps between cops in outposts, etc.
They gave you reasons to jump back to smaller ships once again, use various game mechanics, travel again to systems once forgotten.
But they had a terrible sin: they were fun AND profitable at the same time...
The grind inquisition could not stand the heresy, they picked up the pitchforks in anger, and demanded this to be stopped. People could not be allowed to both make credits and have fun at the same time! If they wanted credits, they had to suffer in penance, and repeat trivial menial tasks a billion times over and over and over and over! And after a short while, FD capitulated, and the missions were "made rare". Rare as in "mostly gone".
Now you spend a lot of time travelling to the @ss end of space in search for one, and risk finding none and having to travel back empty-handed.
Ironically, the only way to effectively get them now, is by cheating the bulletin board by playing login-bingo until you get a bunch of them in the login lottery. A whole new, fun feature which added diversity and encouraged use of multiple game mechanics was nerfed to the ground, and playing login-bingo was once again rewarded. Great job!
