I absolutely will miss it; on page 2 a Dev quote was given which confirms that the missions will not be increased, they're just locking off board flipping, which means that yet again, Frontier have simply tried to slow down progress, rather than actually improve gameplay.
And here's why I'll miss it; Not for the money, or the Naval rank grind; I completed those years ago, when it was much easier; but I'd gladly see it be easier again for those still behind me. My "ranks" aren't more special by making you miserable so you are less likely to catch up with me. If anything, true "explorers" don't worry how easily others follow them once they've found the path, only that they beat the challenge they set for themselves.
No, it's still annoying to see it go because the rest of the game is still so horribly empty and balanced, and freezing the missions whilst blocking board switching will break the Background Simulation. Right now, if you've got two equal sides trying to push a faction, whilst there apparently an influence cap on each individual, it's much easier to simply kill innocents and authority vessels in a system to work against the controlling faction. You can balance that out in a reasonable time just by doing missions. However that's only with Board Flipping; without that it doesn't generate enough that can be completed fast enough. And if you try bounty hunting, there simply isn't enough spawn in an RES, indeed the more you bounty hunt the more the NPCs slowly get replaced with Authority vessels until you're down to a single Wanted NPC maybe spawning one at a time. Which you could always get around be resetting the instance...?
Now, you won't be able to equally defend your system until it falls into one of the War states, and you can fight in a Conflict Zone.
You could also go and collect exploration, but as I'm not up on the BGS changes, I have no idea if that remains practical on Beta. I do know however they've slowed down the whole act to once more please the tiny numbers of players who mistake grind for achievement, so I'm not hopeful that the initial honk without revealing all the system bodies will return the same Influence.
I'm honestly dreading this patch.
