to me all it says is the board doesn't refresh quick enough, have enough missions on it, and not enough variety of the higher payouts.. it needs to be faster and have more.
I don't like sitting in station for half an hour to pick up a bunch of missions of things i want to do in the next hour or so, it really puts me off doing anything, and If i don't get anything decent quick enough , i will go and play something else. I just want to get a bunch of things i am in the mood to do, and go.
To me, all instance swapping shows, is a bad game decision on the board design that, in turn puts me off playing. Anything that stops that even more is a terrible direction for the game that will have other game companies cheering.
The only exception to this I think, would be mining missions. I think it should only take half an hour to clear an entire cargo hold of the big resources, so that it encourages you to fly with a few in your hold, but if you wish to sell up entirely it will take you just a tad longer than a few refreshes, but not much.....
