That is result from announced 2.3 multicrew.
ppl will buy it, play some time util they find it boring and walk away like all my friends did after 50h.
Those number will dip after some time. Last month i checked it many times and average daily playerbase on steam was 3500.
It's an online game. Numbers fluctuate all the time it's what happens.
What the numbers show is a consistent player base that is logging in a most will be having fun (otherwise they would be consistently logging in)
They most definitely DO NOT indicate that ED is dieing or, as the OP implies, is in it's death throws and needs 'saving'
Honestly the comparison in terms of uptake and player numbers is so similar to EVE (you know that other long term online space game) it's crazy. Do a bit of research and you find that it in no way means ED is failing or about to kark it.
Back to the OP. If you are not having fun and have suggestions for improvement then present them in a logical manner and go do something else. Keep abreast of developments and come back if something interests you.
