I can agree about motivation and missions needing to be more interesting. You just need to understand that regardless of game mode, even in solo, you are sharing the same universe as all other players. That is why an SDK or "modding" will not ever exist with Elite Dangerous.This surely is true for those playing Open. I for my part, not being into PvP, avoid Open to the largest degree - only when far outside the bubble I would allow for encounters as they are more likely to be friendly (but then again aren't at all likely to happen).
This is why I was referring to using restricted systems - so it would ideally not interfere with the general shared universe.
The existing mission wrinkle is too little too rarely happening. See, this Ram Tah stuff was a really great experience. And frankly, I am not sure it demands huge efforts to create that kind of missions, especially when you revert to Eighties' style text box communication and multiple choice responses. And yet I was highly entertained at the time (okay, the 200 mio. was obviously a high reward, but then again doing the Sothis passenger run achieves more in less time).
If these missions are entertaining and even provide some story line it would get me back into the game big time. And adding a mechanic of having to pay some running costs for your ships, sort of the concept of the fleet carriers, would keep you busy to have to earn some money and not stack the bank account once you have made it. Not too much, so it doesn't end up in a stupid grind, and only if you actually play to not punish players who take a couple of weeks/months off.
I can imagine that there are wildly differing demands from the PvP fraction primarily playing Open, and those of us who perhaps play PG or Solo to experience ED w/o the PvP part. For me the balance thing is largely irrelevant to my style of play, but the motivation in terms what is there to experience is where it is lacking sorely.
X4 or Everspace, on the other hand, that might be possible.
