I think the main problem with the game as a whole right now is people getting burnt out. Its getting more and more content but people keep getting more exasperated with the community, the staff, and the updates. Also its not like the old features when the community was at its "height" were objectively more fun, they were just newer. It sounds shitty but if people want to have more fun for longer they just need to play less. Its not shocking that a minecraft mmorpg doesn't have enough content to keep people happy for a decade of constant play.
