FDEV needs to do "something" to make Open appealing to all players.
Given the number of players who play Solo because they don't want to meet the players who *don't* shoot at them either - because they can still block the landing pads, or have a silly name, or try to chat, or whatever it is they object to - this is not going to work.
I don't get this idea of "getting more people into Open by changing how it works". By far the most effective thing Frontier has done over the last four years for "getting more people into Open" has been to sell the game in general to more people, thereby increasing the number of players in Open. And by far the second most effective thing they did was improving the instancing so that if you were in Open in the same place as another player you stood a decent chance of actually seeing them.
When I first started playing (a few months after release), I saw about five other players in Open in the first four or five months - most of which was spent in the Alliance core systems, so it's not like I was somewhere obscure. The first time someone tried to talk to me I was so surprised that they'd given up and left the instance before I remembered what key the comms panel was bound to... Nowadays I regularly see that many players in a day. Sometimes I see that many just docked at a single station. And I'm out in Colonia, so these are not "busy" systems by the standards of the main bubble.
There's not a problem in the first place with the number of players in Open. And given the choice between "significantly redevelop the 'rules' of Open so that maybe a net 5% extra players find it appealing" or "add some more general content to all modes so 20% more people buy the game or play it 20% longer having bought it" ... well, I know which I'd rather Frontier spent their time on.
