My 2 pence. The developer needed to set a firmer genre for Elite long ago. It's either an mmo, or it's not. This is based around 2 things.
1. IMO you cannot have in game mechanics (BGS, PP) that can be manipulated from the safety of an offline mode when those mechanics cannot be defended, or can only be swayed by out grinding the oposition, in the interest of fairness any in game mechanics that affect others (think player factions and PP, even exploration) should only be able to be directly defended too.
2. PVE is no challenge, where is the challenge if I have a ship that flattens elite npc's with a 5 second trigger pull, I have had more fun, gained more satisfaction, learned more and made more friends in open over the last two years than all of the previous.
If the community could vote, I would be voting open only, (possibly only once a certain rank is acheived or when out of a larger starter zone as a compromise for newer players)
(also, those that choose to fly open please dont use the block feature unless it's waranted, it does not work as advertised, you can still instance with blocked players if you, or they are in a wing where a player isnt blocked. it just ruins instancing for everyone)
