An idea I had when browsing the World Reset thread.
Ragnarok, AKA end of the world.
Now, I am not going to speak as if I know the logistics and technical issues with running a server, because I don't, however, I think the game would be more interesting and fun long term if we had more regular scheduled World Resets, with two servers, 1 "Old World" consisting of the previous world in a state of "Ragnarok", and a new world, which is a standard world.
So my suggestion is Ragnarok, Worlds would have a set lifespan, 6-12 months, or longer, but with a set time range so we have more consistent resets, annual might be best. However instead of just deleting the old world when a new world launches, the old world server is set on "Ragnarok" mode, during Ragnarok, no new characters can be created, any character who dies cannot reincarnate, and all claim protections are disabled, and hearthfires all extinguished, and sacrificial altars similar to the one we had a few years back appear around the maps, spread out so that 1 village would struggle to claim all of them, having 4-9 would probably be best. Any players who sacrifice themselves to these altars would get a unique hat added to their account, as incentive to for players to stick around long term and fight for epeen swag. When all altars are used, or a set time has passed, the old world will finally end.
This solves the 'late game' problem Haven has, after a certain point, the game becomes a non-stop quality grind with nothing really to look forward too, and many villages die because there isn't really anything to stick around for, as well more regular resets would allow for entry points for people to bring in new friends to try out the game.
