I will preface this by stating that I do appreciate the time and effort that the admin put into new content. These are my opinions, and are not presented as fact.
Anything new and shiny:
Initially, we get all excited and run to buy credits/become involved. Then, the hype disappears as the lackluster becomes evident. This is usually because the cost of participating is way too high, or the effort involved outweighs the payout. For instance, Shipfitting. I was so so excited for this marvelous new thing that I ran out and bought credits for my 12th trade skill. There is no need for me to elaborate on how expensive that is. Anyways, I then found out that the comms required are not regular comms, but prepared materials consisting of rather large combinations of other comms. Then the realization sank in that I'll likely never use this skill, or if I do, it will be very rare. To date, I've yet to use it. There are countless other similar examples. Sailing (cost, chops, time involved), mining, etc.
Large scale events:
These can be very exciting, depending on what they involve. The yearly games are open for anyone to participate in, but let's face it, only the top 5% will win anything in them (aside from maybe design contests). Other events usually consist of players bowling each other over to get mentioned in an events post. Others in the background don't stand a chance when NPCs initiate events cause the loudest ones flock to them and take over. That kills the motivation of many. Have a look at most event posts and you'll generally see the same names mentioned over and over. I'll leave you to consider why.
Old problems/requests overlooked for the newest shiny:
There are many things that players have asked for that have gotten overlooked in favor of the -new-. Things are broken, but hey, we have new! Personally, I'd appreciate most effort being put into the smaller player requests and solving old problems than into the next big credit hole. You might be surprised. Players may actually spend more money here if you address things they complain about. Who wants new features that are either broken, or disappointing?
If it requires long amounts of time, a ton of effort and high cost, with little payout, people simply don't want it. No, I don't want to spend days gathering comms to make more comms for a skill that will rarely be used. No, I don't want to spend hours sailing through chops and dodging seamonsters and pirates to get to an island. Ship trades you say? Ha! Not on your life. That involves sailing to multiple islands, through chops, while dodging people who want to sink me.
We have grown up. Most of us can only spend huge chunks of time in game on our days off. Give us content that is more suited for the casual player. We have jobs, families, and responsibilities.
Involve the average Joe. Players who
are quieter, keeping to themselves. Stop catering to the same select
few. It never hurts to reach out to random players. You want people to keep coming back and potentially fund your
game? Great! Keep them motivated and involved. The last thing you
want is for your players to become bitter over time. Some of the
things I've been seeing leads exactly to that situation.
