But we are still in 2020 so chances are there will be quirks, actually, it is Frontier afterall, it bound to have quirks.
So after... how many years? Combat will become the dominant credit earner (or not)? They just keep cycling the dominant methods since release, first it was REZ hunt,then it was jewllery smuggle, trade routes, then combat bond CG (farm with help of capital class), then trade mission, smuggling mission, then deep core mining, then surface mining... oh well.
At least it kept making all the ships useful from time to time.
