IMO the issue is mostly a branding problem and not a mechanical problem. The whole name community goal is gamey... after all from within the game ittself we are ALL part of the community, both Federation of Pilots members and Non members.
If FD was to change the branding of them, and the word community taken out of the equation then the argument for ban solo from them dissapears imo (or at least it means the argument is the same for all modes, rather than the weekly goals being a special case).
Personally I think it would be wrong, and against the game that was pitched to stop all 3 modes from doing the weekly missions, BUT I do think they could be tweaked somewhat to make them harder, and for instance stop CMDRs from running out of targets in a warzone in open for instance. A warzone should never be out of enemys to kill and ideally if CMDRS were wiping the floor in an instance then the losing side should radio for help, and then the enemy forces react by sending - stronger - reinforments. This should in theory keep it fun regardless of the strength of the CMDRs in an instance..
I also would not have a problem with having the payouts change so that it is top 5% in each group, the top 40% in each group etc gets the pay outs (but you can only "score" in one of them so cant be top 5% in all 3). IMO this stops the perceived unfairness of players "winning" the extra cash in solo whilst still affecting the mission.
but, imo like it or not (and I can see why some may not like it) solo has always promised to affect the galaxy in the same way that open does and i truly hope this never changes.
I am not sure if what I put above could be seen as a fair compromise or not?
Agree about the "community" bit of the name.
Some people seem to have decided that it means the open community as opposed to the private group community or the solo community.
My guess is FD meant it as the ED game playing community as a whole.
