I think the bulk of the angst comes from the botched expansion (2.3) that promised much and delivered little in terms of actual gameplay improvements. Not to mention the networking problems we've all been experiencing the last couple of weeks since 2.3 dropped. All I've done with my elite time is fiddle about with Graphics settings as the game doesn't run as smoothly as it used to even though the graphical assets haven't been altered.
I'm sure that I am not the only one that is suffering with the effects of nerf to income, nerfs to gameplay, a game that reward you for doing what the developers want as opposed to 'blaze your own way,' (passenger missions anyone), nerf to the networking (particularly bad today with it taking ages to load systems in witch space etc) and of course beige worlds, that are fundamentally the same with nothing interesting to look at on them. No wonder the OP is annoyed and I feel his pain, I'm sure many of us do.
All of the above adds to the general feeling that ED was a better quality game in it's past and that the focus of the 100 strong developer team at FD isn't ED anymore, it's actually localising the game for other platforms and expanding the marketing base for the vanity store. We know it's a matter of record that FD were disappointed with sales of Horizons and something changed at FD between 2.0 and 2.1 the games direction fundamentally changed from bold new features and massive amounts of development time to bare bones features and minimal amounts of dev time.
That's what the OP is annoyed about and to a mild degree so am I. As far as I am concerned 2.4 had better be extraordinary we have been promised much and given little. If 2.4 doesn't bring about an improvement in the core game as promised, if existing features aren't expanded (multi-crew for explorers, engineer positions in ships etc) then FD is doomed.
