Lately less and less interested. There's a handful of issues in retrospect.
Greedy new implementations of profitable activities. (Nuff said. )
Lack of novel explorable, static content (waiting years for a certain town starts with a b and ends with aboard)
Fixes on current issues slowing or absent (appears as lag, but optimization needs serious attention, not to mention a ton of minor issues that we've just come to live with and accept)
Removal of staff contact in game (they seemed to be so present and really part of the community earlier. Now they're practically invisible)
Various divisions of the playerbase causing regions to become uninhabitable (language barriers, those military kids taking over wide swaths of area with Noob accounts advertising their recruitment for example )
Homogenization of events (easter coming up. Gonna look just like the last 5 times, and I'm not interested in an undefined mount enough to grind 100 eggs with my limited free time. That said, Halloween has done something right with the regional open area, but failed so poorly with the grab bags just adding more to the list. Items were special when you got them one year and then they were gone. Last year I dropped all my candy on furniture bags and got absolutely nothing fresh.)
UI ux needs an upgrade. I've asked that before, and it was tweaked, but the main menu system still looks like an Ms paint job over top of a folder system. Could be greatly improved.
What has been good?
I liked the 10th anniversary. Really well implemented, to the point I was hopeful that the game would just be riddled with time portals forever.
The minish cap style shrinking and growing content at that one nexus. We need more interesting mechanics like this. Stuff that is neat and engaging and not just recolors of pre existing content (blah blah not "classic" - there were weapons, adventures, collectibles, and far more collaboration in the early days!)
Reflecting on the time I've spent, the most enjoyable parts of the game have been novel, innovative, fresh, and have gotten players working together to tackle whatever the objectives were. Anyone remember the release of big city? That first two or three days it was mysterious and fun.
Sustainable, modular content with that sense of exploration and cooperation is what we need more of.
