Ehh, that's just incentives that encourage idling away from anyone, pretty much defeating the point. If somebody wants to avoid others but get these rewards, they'll just be avoiding others in Open to do so.I would say that buffs or rewards, as opposed to content gating, would be my preference. Increased rewards for existing content, or even new rewards for time spent in open. Say a new ship variant comes out as a "veteran reward" of sorts, which requires 20-40 hours flying time (not docked time) in open. Even if you spend it out in the black, that's fine.
At the end of the day there will be folks who will game any system, and you can't beat em; at least I can't, as they're probably all smarter than me lol. But what you can do is at least try to create the incentive and hope that even a few folks will be lured to the goodness.
I would rather find ways to encourage players to have nteractions with each other, rather than just corral them into a specific mode.
