Funny how FDEV shut down the infinite-gold asteroids and stripped the credits off anyone who used those asteroids then when the profit from that activity was much less than what you can make on a single Smeaton run (or whichever other stations are located far from jumpin points).
The cash vs time invested is off the charts and basically makes all other forms of earning cash pointless. That is the point.
Normally I don't do this, but I haven't read past page 1, so apologies if this is a repeat:
I've never UA bombed anything, but as I understand it, if someone did UA bomb Smeaton (and other such places), the cash cow is gone until someone fixes the station. That would be how griefers can affect you, regardless of what mode you play in.
On to your OP:
Frontier has a number of options when it comes to this kind of thing, but I actually like that these missions exist, and that they pay as much as they do. It does take some time investment, and doing these missions, as you said, earns a lot of credits in a very short amount of time. This way, at least, players have options - if you want to make a lot of credits, go do this thing over here for a bit, and then spend the rest of your time in game playing however you want, and doing whatever you want, instead of being concerned about how much it pays. In some ways, you could also extend that to flying whatever you want or like, instead of whatever is most efficient, because again, if making credits is your goal, go do this for a bit.
The alternative, is for Frontier to fight the never-ending battle of trying to make sure most (or all) of the activities in the game have comparable payout potential. Considering how many different activities there are, this just seems like a dog chasing its tail - just as amusing, and just as useless. One cash cow in the game that doesn't involve exploits (anyone's opinion on board flipping is irrelevant, since Frontier has not determined it to be an exploit), takes some time to accomplish, and provides a really good return on that time investment. One thing that can be tweaked, as necessary, instead of trying to balance a slider for each activity in the game.
There is also something else that's important - as the game progresses, Frontier needs to build in ways for a brand-new player to catch up, and get involved with whatever is currently happening in the game in a meaningful way. This means reducing the initial ramp time, which is something that all MMO's do, in some way or other. Frontier has already increased the new Commander income potential substantially since I started playing, and these passenger missions (and to a lesser extent, the fact that the Ram Tah mission can be repeated) provide new Commanders with a way to get into the current game fairly quickly. This is, actually, really, really important. Those are just two of the ways - there are more.
I get that it doesn't make sense - do them or don't, that choice is yours every time you load up the game. If you are doing them, then complaints are hypocritical, don't you think?
How many runs did you do before making this post, by the way?
